Definition of Bad hit

A fast paced offensive game similar to 9-ball but only using balls numbered 1 through 7.
Pocketing the 7-ball wins the game. Under the current pro rules of 7-ball, any missed shot gives your opponent ball-in-hand.

A shooter's body position and posture during a shot.

The point in match play where both players (or teams) need only one more game (frame) victory to win the match or race.

Used when describing perfect cue ball position play.

This is the apex ball in the triangle, racked on the foot spot in a normal game.

This is the portion of the cue you would be holding if there was no wrap or grip present. This is the position where the best gripping power can be generated, and is situated below the forearm and above the butt. This portion is often covered with a wrap, but other times left bare to create a simple seamless style.

This is a shot involving contact between the cue ball and an object ball which allows the cue ball to contact another object in order to sink a pocket with the second object ball.

This the area behind the pocket points before the pocket. The ball can get behind here and rest waiting to be pocketed, or the cue ball can get corner hooked in this location. Different tables feature a smaller or larger area here which can make these situations more or less achievable.

This is the act of keeping your ball location advantages the way they are, and not allowing your opponent to even things out in the game of one pocket.

One-pocket (often spelled one pocket) is a two-player (or -team) pocket billiards (pool) game. The object of the game is to score points by pocketing (potting) pool balls into specific pockets. A point is made when a player makes any object ball into that player's designated pocket. The winner is the first to score an agreed-upon number of points (most commonly 8). The player making the break shot (typically after winning the lag) chooses a foot corner pocket for the rest of the game; all of that shooter's balls must be shot into that pocket. All of the opponent's balls must be made in the other foot corner pocket.

A unit of scoring, in games such as snooker and straight pool with numerical scoring.
A unit of scoring, in team matches in leagues that use numerical scoring instead of simple game/frame win vs. loss ratios.
Another term for knuckle / tittie.

This game is played on a smaller octagonal table filled with bumpers in the middle and two more bumpers surrounding a hole on each side of the table. The game is played by trying to sink the balls into the opposite pocket by hitting the object ball directly instead of using a cue ball.

Refers to a person gambling when he has no money. As in, "That jerk can't pay up, he was shooting air barrels the whole time".

Adjectival expression for a player's deadly game; "watch out, he plays jam up.

A form of doubles play in which the two team members take turns, playing alternating shots during an inning (i.e. each team's inning consists of two players' alternating visits, each of one shot only, until that team's inning ends, and the next team begins their alternating-shot turn.) Effective scotch doubles play requires close communication between team partners, especially as to desired cue ball position for the incoming player. Like "english", "scotch" is usually not capitalized in this context. The term is also used in bowling, and may have originated there.

A British term for someone with little experience or understanding of the game, who may be skilled at potting individual balls but does not consider tactics such as position or safety; "he's a potter not a player." See also banger.

Chiefly British: The rail at the Top of the table. Compare foot rail; contrast Bottom rail.

Used by itself often with "low" and "high": "that's a low-percentage shot for me", "I should really take the high-percentage one".

When the cue ball is tucked behind the corner of a pocket, therefore not allowing a direct shot at the object ball without it bouncing of the corner of the rail.

Also bar rules, pub pool, tavern pool. Pool, almost always a variant of eight-ball, that is played by bar players on a bar table. Bar pool has rules that vary from region to region, sometimes even from venue to venue in the same city, especially in the U.S. Wise players thus ensure understanding of and agreement to the rules before engaging in a money game under bar rules. Typical differences between bar pool and tournament eight-ball are the lack of ball-in-hand after a foul, the elimination of a number of fouls, and (with numbered ball sets) the requirement that most aspects of a shot be called (including cushions and other object balls to be contacted) not just the target ball and pocket. Bar pool has evolved into this "nitpicky" version principally to make the games last longer, since bar pool is typically played on coin-operated tables that cost money per-game rather than per-hour. Competitive league pool played on bar tables, however, usually uses international, national or local/regional league rules, and is not what is usually meant by "bar pool".

This is when you strike a cue ball off center to gain control on the movement on the cue ball.

Also striped ones, striped balls. The ball suit (group) of a fifteen ball set that are numbered 9 through 15 and have a wide colored bar around the middle. Compare bigs, highs, yellows, overs; contrast solids.

Also known as a "Dirty Defense" or "Dirty Foul". To intentionally miss a shot (that results in a foul) in order to create a position for the cue ball that makes it hard for the other player to execute their shot. Not to be confused with a "Safety", since a safety is a legal hit.

In snooker, the colour ball that is worth three points, being the second-least valuable colour behind the yellow. It is one of the baulk colours.
