Bankroll
Money that you can afford to set aside and invest for betting purposes only. Learn more about how to manage your bankroll here.
Chalk
The betting favourite – more often one that is heavily favoured to win.
Chasing Losses
The act of making reckless bets you otherwise wouldn’t have, just because you lost a bet.
Favourite
The side that is projected to win by oddsmakers.
Juice
The commission a sportsbook earns on each bet. If the odds are even, a sportsbook will generally make the bet -110 so they keep the -10.
Live Betting
Betting on a game while it is unfolding. Also referred to as “in-play betting”.
Lock
A term used by inexperienced bettors to describe an “easy winner”.
Tip: There is no such thing as a “lock”. Anything can happen in sports – injuries, bad ref calls – so proper bankroll management is essential.
Moneyline
Betting a team to win the game straight up.
Mush
A gambler who is considered to be bad luck.
Parlay / Accumulator
A type of bet where you combine two or more bets, earning a higher payout if all of them win. If one leg loses, the whole parlay loses.
Pick’em
A game in which there is no favourite or underdog. Oddsmakers believe neither side has a clear advantage.
Push
The result of a tie between the bettor and the sportsbook. The bettor is refunded their money and doesn’t lose any juice.
Steam
When a sudden and large line movement occurs across the betting marketplace – caused by a large amount of money being placed on a certain bet.
Underdog
The side that is projected to lose by oddsmakers.
Unit
A simple way of measuring bet size regardless of bankroll. 1 unit = 1% of your bankroll. With a $10,000 bankroll, a 1 unit bet = $100, a 5 unit bet = $500, and so on.
Action
A bet or wager. “I want action on this fight” means you want to bet on it. Also used to describe the betting activity on a particular market – “there’s heavy action on the favourite” means a lot of money has been wagered on them.
ATS (Against the Spread)
A result measured relative to the point spread rather than win/loss. Less relevant in MMA (which uses moneylines rather than spreads) but common in NFL, NBA, and other team sports. In MMA contexts, ATS sometimes refers to a fighter’s record against the implied market probability.
Backdoor Cover
When a team or fighter covers the spread or achieves the betting result due to meaningless late action – a finish in the final seconds that changes the betting outcome after the result is no longer in doubt. Generally frustrating for bettors on both sides.
Beard
Someone who places bets on behalf of another person to conceal their identity from the sportsbook. Used by sharps whose accounts have been limited to continue getting bets on at full stakes.
Buying Points
Paying extra juice (vig) to move the spread or line in your favour. In NFL betting, you might pay -130 instead of -110 to move a spread half a point. Less common in MMA where spreads don’t exist, but occasionally available on round totals.
Circled Game
A game or fight where the sportsbook has reduced the maximum betting limits, usually due to injury news, uncertainty about a fighter’s status, or other factors that increase the book’s risk exposure. Circled fights often have lower limits and may have limited market depth.
Closing Line Value (CLV)
The difference between the odds you bet at and the final odds at fight time. If you bet a fighter at +180 and the line closes at +130, you have positive CLV – you got 50 points better than the closing price. Positive CLV over a large sample is the strongest indicator of a genuine long-term betting edge. See: CLV Explained.
Contrarian Betting
Deliberately betting against public opinion to find value on the side the market has overcorrected on. Because sportsbooks shade lines toward the public’s preferred side, the unpopular side often offers better implied value. Works best in high-profile fights where public bias is strongest.
Cover
To win against the spread. In spread betting, a favourite covers by winning by more than the spread; an underdog covers by losing by less than the spread (or winning outright). In MMA moneyline betting, there is no spread to cover – you either win or lose.
Dead Heat
A tie or draw between two fighters. In UFC, a majority or split draw counts as a dead heat for betting purposes. Most sportsbooks settle a moneyline bet as a push (stake returned) on a draw. Three-way moneylines price the draw as a separate outcome.
Decimal Odds
An odds format common in Europe, Australia and Canada. The decimal represents the total return per unit staked, including the stake. Evens = 2.00. A -150 American odds favourite = 1.67 decimal. A +200 underdog = 3.00 decimal. To calculate profit: (decimal odds × stake) − stake.
Dog
Short for underdog – the fighter or team expected to lose according to the market. Dogs are always priced with positive American odds (+). Backing dogs at the right price is one of the primary sources of long-term profit for skilled MMA bettors.
Each Way
A bet type common in horse racing and golf where you bet on both the outright win and the fighter/player to finish in a top placing. Rarely used in MMA betting. Occasionally available on UFC tournament-style markets or multi-fighter exotic bets.
Expected Value (EV)
The average return per bet over a large number of repetitions. A +EV bet has a true probability higher than the odds imply – it makes money in the long run. A -EV bet loses money in the long run regardless of short-term variance. Every bet should be assessed for EV before being placed.
Fade
To bet against a particular fighter, tipster, or public opinion. “Fading the public” means betting the unpopular side. Sharps often fade heavy public action because sportsbooks shade lines toward public-backed fighters, creating value on the other side.
Fight Goes the Distance (FGTD)
A prop bet on whether the fight reaches the final round without a stoppage. Available as yes/no at most sportsbooks for all UFC fights. Particularly valuable in fights involving high-finishing strikers or submission specialists against defensively vulnerable opponents.
Fractional Odds
The traditional British odds format, expressed as fractions (e.g., 4/1, 11/10). The numerator is profit and the denominator is stake. 2/1 means win $2 for every $1 staked (profit only, not including stake returned). Evens = 1/1. A -110 American favourite ≈ 10/11 fractional.
Futures
A bet on an outcome that will be decided in the future, such as who will be UFC champion at year end or who will win a specific weight class. Futures carry high variance (long waits, many variables) but occasionally offer strong value when you identify a fighter whose championship odds are undervalued.
Handle
The total amount of money wagered on an event or across a sportsbook’s book. A high-handle fight is one where a large volume of bets has come in. High-handle events typically have more efficient pricing because more sharp money has been processed into the line.
Handicapper
Someone who analyses and rates the probability of sporting outcomes for betting purposes. Can refer to a professional who sells picks or someone who handicaps (analyses) fights for their own betting. A legitimate MMA handicapper should have a publicly verified track record.
Hedging
Placing a bet on the opposite side of an existing wager to reduce risk or lock in profit. Common with futures bets – if you backed a fighter at long odds to become champion and they’ve reached the final, you might hedge by betting their opponent to guarantee a profit regardless of outcome.
Implied Probability
The win probability built into a set of odds by the sportsbook. Converting odds to implied probability lets you compare the market’s view against your own assessment. If the implied probability is 60% but you believe the true probability is 70%, there is positive expected value. See: How to Read UFC Odds.
Kelly Criterion
A mathematical formula for optimal bet sizing based on your edge and the odds. Full Kelly = (bp − q) / b, where b = decimal odds minus 1, p = probability of winning, q = probability of losing. Most serious bettors use fractional Kelly (half or quarter Kelly) to reduce variance while still maximising long-term growth.
Limit
The maximum amount a sportsbook will accept on a single bet. Recreational books typically have lower limits ($500-$2,000 on UFC fights). Sharp books like Pinnacle have significantly higher limits. Winning bettors often find their limits reduced or accounts restricted by recreational books over time.
Line Movement
The change in odds from the time a line opens to when it closes. Significant movement toward an underdog (price shortening) typically indicates sharp money coming in on that side. Tracking line movement tells you where informed money is going, though it requires context to interpret correctly.
Method of Victory (MOV)
A prop bet on how a fight will end – by KO/TKO, submission, or decision – for a specific fighter. One of the most commonly bet MMA prop markets and often less efficiently priced than the main moneyline. See: MMA Prop Bets Explained.
Middling
Betting both sides of the same market at different times at prices that create a window where you can win both bets. Requires line movement between your two bets. Uncommon in MMA due to the binary nature of moneylines, but occasionally possible on totals markets when lines shift significantly.
No Contest (NC)
A UFC result where the fight is declared no contest, usually due to an accidental foul, failed drug test, or medical stoppage. For betting purposes, most sportsbooks void all bets and return stakes on a no contest result. Check individual book rules as policies vary.
Opening Line
The first odds posted by a sportsbook for an event. Opening lines are typically set with lower limits to test the market before adjusting. Sharp bettors often target opening lines to get best value before the market has been shaped by significant action.
Over/Under
A bet on whether the total rounds in a fight will be over or under a specified number set by the sportsbook. The most common UFC total is 1.5 or 2.5 rounds. Over typically implies a decision or late finish; under implies an early stoppage. See: MMA Prop Bets.
Puckline / Runline
Spread betting variants used in hockey (puckline) and baseball (runline). Not directly applicable to MMA, but understanding these formats helps when sports betting lingo crosses over from other markets.
Return on Investment (ROI)
Total profit divided by total staked, expressed as a percentage. A 10% ROI over 200+ bets is elite-level performance. ROI is more informative than raw profit/loss because it accounts for how much was risked to generate that return. See: Units and ROI Explained.
Round Betting
A prop bet on which specific round a fight will end in. Higher odds than method of victory bets due to the precision required. A fighter might be -200 to win the fight but +450 to win in Round 1. Grouped round betting (Rounds 1-2) is more achievable and often priced attractively.
Sharp
A professional or highly skilled bettor whose action moves lines. Sharps bet large amounts based on rigorous analysis and consistently show positive results over large samples. Sportsbooks track and sometimes limit sharp bettors. “Sharp money” refers to bets placed by these informed bettors.
Square
A recreational or casual bettor who typically backs popular fighters, big names, and chalk without deep analysis. Squares make up the majority of betting volume on high-profile fights. Sportsbooks build their lines partly around square tendencies, creating value on the other side in some situations.
Tipster
Someone who sells or shares betting picks. In MMA, legitimate tipsters should have publicly verified results on platforms like betMMA.tips or bettin.gs. Unverified tipsters – those who only share social media screenshots – have no credible track record. See: Best MMA Tipster Guide.
Tout
A derogatory term for a dishonest tipster who manipulates their results, sells picks of no genuine value, or employs fraudulent practices (like splitting a subscriber list and sending opposite picks to each half). The MMA betting space has many touts – verified third-party records are the only reliable protection against them.
Value Bet
A bet where the true probability of the outcome is higher than the implied probability in the odds – i.e., the odds are better than they should be. Value betting is the foundation of long-term profitable betting. A bet can be a value bet and still lose; a losing bet can still have been a value bet if the analysis was correct.
Vig (Vigorish)
The sportsbook’s built-in margin – the percentage by which all implied probabilities add up to more than 100%. Also called juice or the rake. On a typical UFC fight, the vig is 3-6% depending on the book. See: What Is the Vig?
Weight Cut
The process of reducing body weight before a UFC weigh-in, typically through dehydration and caloric restriction. Fighters often cut 10-20+ lbs in the days before a fight and rehydrate before competing. Severe cuts affect performance, particularly cardio and chin. A known heavy cutter on short notice is a useful betting angle.
