24 Random Essential Billiards Terms

A player's turn at the table, also known as an inning.
When a ball is given as a handicap it often must be called (generally tacit). A wild handicap means the ball can be made in any manner specifically without being called.

The non-red colored ball meant to be pocketed in a game of snooker, or the next ball meant to be pocketed in a particular game.
The wrap is situated over the handle of the cue, below the forearm and above the butt. Common materials used are Irish linen, leather, or cork. These materials make sense, because they provide a sure grip, long life, and help to absorb moisture from the hand when you are sweating through a difficult rack. In addition, wraps are used to compliment the color or style of the cue stick and to elegantly complete the look.
Netted or cupped pockets that do not return the balls to the foot end of the table by means of a gutter system or sloped surface beneath (they must instead be retrieved manually).
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.
This is any game of pool played with money on the line. You can "put some action" on the game.
A term applied especially in snooker for a type of double off three cushions, e.g. around the baulk colours and into a centre pocket. Such a shot is very difficult to make and would not normally be played as anything more than a shot for nothing.
Also dead ball shot. A shot intended to slow down or "kill" the cue ball's speed as much as possible after contact with an object ball; usually a shot with draw, often combined with inside english. It is often shortened to kill.
Chiefly Australian: Same as a force follow shot.
The desired angle that must be created between the path of the cue ball and the path of the object ball upon contact to pot the object ball. It is usually measured to the center of the pocket. See also aiming line.
The International Pool Tour is a professional sports tour created in 2005 by Kevin Trudeau and hosted by Rebecca Grant. It aims to elevate pool (pocket billiards) to the level of other modern sports.
The person in charge of the game whose primary role is to ensure adherence by both players to the appropriate rules of the game being played. Other duties of the referee include racking each frame, re-spotting balls during the course of a game, maintaining the equipment associated with the table (e.g. keeping the balls clean), controlling the crowd and, if necessary, controlling the players. Formerly sometimes referred to as the umpire.
Describing a situation where a pot is made more difficult, either by a pocket being partially blocked by another ball so that not all of it is available, or the cue ball path to the object ball's potting angle involves going past another ball very closely.
This shot refers to using heavy follow to push through an object ball on its way to its destination.
The normal phenomenon where the object ball is pushed in a direction very slightly off the pure contact angle between the two balls. Caused by the friction imparted by the first ball sliding past or rotating against the other ball.
Linen made from flax and produced in Ireland which is often used to wrap the gripping area of the butt of a cue.
Nine Pin (also known as Goriziana) is a carom billiards game. The game has nine pins in the center of a table. It is played by two teams of 1 or 2 players. Three balls are used of which two are cue balls. Each team (or each player) aims to hit their opponent's ball and from there score points by hitting onto the red ball and also by making the opponent's and/or the red ball knock over the pins.
A shot aimed so that the center of the cue ball is in line with the edge of the object ball, eclipsing half of the ball. "Hit it just a little thinner than half-ball." Assuming a cling does not occur, the shot will impart post-contact momentum on the object ball in a direction 30° (which is arcsin(1 - x), where x is the fraction of object ball eclipsed: ½ in this case) off the direction of the cue-ball's pre-contact momentum. Also notable because the carom angle the cue ball takes is more consistent than at other contact points.
A shot in which the cue ball is driven to one or more rails (cushions in British English) before reaching its intended target-usually an object ball. Sometimes also known as "Kick Out" or "Skid" (British)
On two piece cues, the area of the cue between the joint and the wrap.
This refers to a shot that is not banked, does not hit a rail and goes into the pocket without contacting any other balls on the table.
Same as gutter table. A table with a ball return system, as opposed to a drop pocket table.
