Glossary of racing and party-pool terms

Racing has been coining slang since the 1800s, and half the fun of a derby party is talking like you belong at the rail. Every term below is defined the way it's used at your party — in points, among friends.

The bets

Win: A bet that your pick finishes first. The simplest ticket and the anchor of every pool.
Place: A bet that your pick finishes first or second. Pays the same either way, and less than a win bet would, because it cashes more often.
Show: A bet that your pick finishes in the top three. The safest and smallest-paying of the straight bets.
Across the board: Three equal bets on one entrant — win, place, and show — bought together. If your pick wins, all three cash; second, two cash; third, one.
Straight bet: Any single bet on a single outcome, as opposed to a box or wheel bundle.
Exacta: Pick the first two finishers in exact order. See exotic bets explained.
Quinella: Pick the first two finishers in either order. One ticket covers both arrangements.
Trifecta: Pick the first three finishers in exact order. Rarely held, loudly celebrated.
Superfecta: Pick the first four finishers in exact order — a racetrack classic beyond even the trifecta.
Box: A bundle covering every ordering of your chosen entrants. A three-horse trifecta box is six tickets, and costs like it.
Key (banker): An exotic built around one anchored entrant — "key the 4 on top" fixes 4 first while others rotate behind.
Wheel / part wheel: An exotic that fixes one position and takes all (or several) entrants in the rest.

The board and the math

Parimutuel: From the French pari mutuel, "mutual bet": all stakes of one type share a pool, winners split it. No bookmaker, no house line — see how it works.
Pool: The combined stakes for one bet type. The win pool, place pool, and exacta pool are separate pots with separate payouts.
Tote / totalisator: The machinery (now software) that totals every pool continuously and computes live odds.
Toteboard: The display of the tote's numbers — trackside it's the infield board; at your party it's the TV. See reading a toteboard.
Odds: Profit per unit staked, as implied by the current pool. 5–1 means five points of profit per point staked if your pick wins.
Odds-on: Odds below even money, like 4–5: profit is smaller than stake. The mark of a heavy favorite.
Morning line: A track professional's pre-betting estimate of how the public will bet. A forecast of the crowd, not a payout promise.
Takeout: The percentage a commercial track removes from each pool before payouts, funding purses and operations. A friendly points pool typically takes nothing.
Rake: PartyMutuel's optional host-set percentage carved from a pool — in a points game, a side pot to award for best hat or wildest pick.
Breakage: The pennies a track keeps by rounding payouts down to a nickel or dime increment. Point pools skip it and pay exact.
Handle: The total staked across all pools — the headline size of the day's action.
Payout: What a winning ticket returns, stake included. US tracks traditionally quote it per $2; PartyMutuel quotes points.
Overlay / underlay: A pick whose odds look bigger (overlay) or smaller (underlay) than its real chances deserve. At a party this mostly means "nobody else noticed the cool name."
Minus pool: A rarity where so much backs one outcome that mandated minimum payouts exceed the pool — a real track's problem, never a points pool's.

The race

Card: The full slate of races at one meeting. The famous race is one line on a long card.
Post time: The scheduled start of a race — and the moment betting closes. The one deadline your party must respect.
Post position: An entrant's stall number in the starting gate, shown on the board and the party sheet.
Field: All entrants in a race. At your party, the "field" might be horses, award nominees, chili entries, or rubber ducks.
Favorite / chalk: The most-backed entrant, carrying the shortest odds. Betting favorites is "playing the chalk," a phrase from the era of odds chalked on boards.
Longshot: A lightly backed entrant at long odds. The engine of every great party story.
Scratch: An entrant withdrawn before the start. Scratched entrants' tickets come out of the pool so no stake is stranded.
Silks: The jockey's colors. PartyMutuel assigns each entrant a silk color so the board reads at a glance.
In the money: Finishing in the top three — the finishes that cash straight bets.
Dead heat: An exact tie at the wire. Tracks split the affected payouts; parties should agree on a rule before post.
Photo finish: A finish close enough to need the camera. Wait for it.
Official: The stewards' confirmation of the final order after any photos or inquiries. Enter party results only when the broadcast says official.
Inquiry / objection: A stewards' review of possible interference, which can reorder the finish after the race.
Maiden: A horse (or party guest) yet to win their first race.

The party

Scorekeeper: What PartyMutuel is: an app that tracks points and does parimutuel arithmetic for private social games. It cannot take, hold, move, or pay out money — no real money, ever.
Party code: The six-character code (with QR) a host shares when going live. Guests join from their phone's browser with the code and a name — no account needed.
Host: The guest running the show: enters the field, opens and closes betting, records official results — and is responsible for keeping the game legal where they live.
Stash: A guest's starting allotment of points. Equal stashes keep the leaderboard honest.
Ticket: One recorded pick: entrant(s), pool, and points staked.
Void: A host's removal of a mistaken ticket before results — the party equivalent of the teller canceling a mispunched bet.
Settle up: Whatever your group agrees the final scoreboard means — trophy, bragging rights, dish duty — arranged in person, offline, entirely among friends. The app only ever supplies the scoreboard.
