NBA Prop Betting Glossary: Key Terms for UK Bettors
Available in US
The first time someone told me they’d “steamed a block prop after CLV confirmed their edge,” I nodded along pretending to understand while mentally lost. Prop betting has its own vocabulary, much of it borrowed from American sports betting culture and unfamiliar to UK bettors raised on football accumulators and horse racing terminology. This glossary translates the jargon into plain English.
Understanding terminology isn’t just about avoiding embarrassment – it’s about accessing information. Betting forums, analytical resources, and experienced bettors communicate using this vocabulary. Without it, you’re locked out of conversations and content that could improve your betting.
Player props now comprise 25-30% of total basketball handle at major sportsbooks. The market has developed sophisticated language to match its sophistication. Learning that language accelerates your development as a bettor.
Terms A Through G
Alternate line – A prop line different from the primary offering. If the standard line is over/under 24.5 points, alternate lines might offer 22.5 or 26.5 at adjusted odds. Bettors use alternates to adjust risk/reward based on their confidence level.
Bankroll – The total money specifically allocated for betting. Proper bankroll management treats this as separate from other finances, sized at amounts you can lose completely without affecting your life.
Closing line value (CLV) – The difference between the odds you bet and the odds at game time. Consistently betting at better odds than closing lines indicates sharp betting; the market moves toward correct prices, so beating them suggests you identified value.
Correlation – The relationship between different betting outcomes. A player’s points prop correlates with his team’s total – high team scoring usually means high individual scoring. Same-game parlays must account for correlation in pricing.
Edge – Your advantage over the market, usually expressed as percentage. A 5% edge means you expect to win 5% more often than the odds imply. Sustainable betting requires identifying genuine edges rather than perceived ones.
Expected value (EV) – The average outcome of a bet over infinite repetitions. Positive EV bets profit long-term; negative EV bets lose. Most recreational bettors make negative EV bets; skilled bettors seek positive EV consistently.
Fade – Betting against something – a player, a trend, or popular opinion. “Fading the public” means betting opposite to recreational money flow, often toward unders or unpopular positions.
Graded – A bet that has been settled and had its result recorded. Tracking services report performance across graded picks to show historical accuracy.
Terms H Through P
Handle – The total amount of money wagered on a market or at a sportsbook. High handle indicates popular markets; low handle suggests niche markets that might be less efficiently priced.
Hold – The percentage of wagered money the bookmaker keeps as profit. Same-game parlay hold rates have increased from 6-7% to 9-11% as operators extract more margin from combination bets.
Juice (or vig/vigorish) – The bookmaker’s commission built into odds. Standard juice is around 10% – you bet £110 to win £100 at American odds, or see odds of 1.91 instead of 2.00 at decimal odds. Lower juice means better value for bettors.
Line – The number set by bookmakers that divides over from under outcomes. A points line of 24.5 means the over wins at 25+; the under wins at 24 or below. Lines move based on betting action and new information.
Line shopping – Comparing odds across multiple bookmakers before betting. Different operators set different lines; shopping ensures you bet at the best available price.
Lock – A bet presented as certain to win. In reality, no bets are locks – the term is marketing rather than analysis. Anyone selling locks is selling overconfidence.
Moneyline – A bet on which team wins outright without point spread. Not a prop term specifically but foundational to understanding how props differ from game-level markets.
Over/under – The two sides of a prop bet. The over wins if the player exceeds the line; the under wins if they fall short. The .5 in lines eliminates pushes.
PRA – Points plus rebounds plus assists combined into a single prop total. PRA props smooth variance compared to individual category props.
Push – A bet that lands exactly on the line, resulting in returned stakes rather than win or loss. Half-point lines (.5) eliminate pushes; whole-number lines create push potential.
Terms Q Through Z
ROI (return on investment) – Your profit as a percentage of money wagered. An ROI of 5% means you’ve profited £5 for every £100 bet. Sustainable prop betting produces single-digit ROI over large samples.
Sharp – A professional or highly skilled bettor whose action bookmakers respect (and often fear). Sharp money moves lines; recreational money gets absorbed. Sharps bet early and find value before markets correct.
Square – A recreational or unsophisticated bettor. Squares tend to bet overs, favourites, and popular teams. Bookmakers profit from squares; they limit sharps.
Steam – Rapid line movement caused by significant betting action, usually from sharps or syndicates. Steam moves indicate the market has identified something – possibly value, possibly injury news, possibly modelling output.
Tout – Someone who sells betting picks. Quality varies enormously; many touts sell hope rather than edge. Verify historical performance before paying for picks.
Two-way contract – An NBA contract type allowing players to shuttle between the NBA roster and G League affiliate. Two-way player props carry manipulation concerns following several scandals.
Unit – A standardised bet size, typically 1-2% of bankroll. Bettors track performance in units to compare across different stake sizes and time periods.
Usage rate – The percentage of team possessions a player uses through shots, free throws, or turnovers while on court. High usage correlates with scoring volume, making it essential for points prop analysis.
Variance – The statistical spread of outcomes around expected value. High-variance props like blocks swing wildly game-to-game; low-variance props like points are more predictable. Bankroll management must account for variance.
Vig – See juice. Short for vigorish, the bookmaker’s built-in edge on every bet.
Applying the Vocabulary
Now that sentence from my opening makes sense: “I steamed a block prop after CLV confirmed my edge” means the bettor placed a bet quickly when sharp action moved the blocks line, having verified through closing line value tracking that their analysis consistently identifies genuine advantages in blocks markets.
The comprehensive analytical framework in our basketball prop bets guide applies these terms in practical context. Understanding vocabulary is step one; applying it to actual betting is where value materialises.
Terminology evolves as markets develop. New prop types create new terms; platform changes introduce new jargon. Stay current through betting forums and analytical communities where language develops alongside strategy.
What does juice mean in prop betting?
Juice, also called vig or vigorish, is the bookmaker’s commission built into betting odds. Instead of offering true 2.00 odds on a 50/50 proposition, bookmakers offer around 1.91 on each side, ensuring they profit regardless of outcome. Lower juice provides better value for bettors; comparing juice across bookmakers is part of effective line shopping.
What is the difference between handle and hold?
Handle is the total amount of money wagered on a market. Hold is the percentage of that wagered money the bookmaker keeps as profit. If bettors wager £1 million total and the bookmaker profits £80,000, the hold is 8%. Same-game parlays typically have higher hold than straight bets because correlation pricing allows larger bookmaker margins.
