24 Random Essential Billiards Terms

A slang term for a cue, usually used with "piece", as in "that's a nice piece of wood".
This is the ball that sits in the front, or apex, position in the rack.
This is a type of shot where the cue ball goes off the rail before it heads to contact the object ball, thus giving the cue better position in some shots.
Displacement of the cue ball's path away from the parallel line formed by the cue stick's direction of travel; occurs every time english is employed. The degree of deflection increases as the amount of english applied increases. It is also called squirt, typically in the United States.
Also sidespin, side-spin, side. spin placed on the cue ball when hit with the cue tip to the left or right of the ball's center; usually called english in American usage. See english, in its narrower definition, for details on the effects of side spin.
Any standard pool cue used to shoot the majority of shots in a match.
This refers to the distance of deflection that the ball comes off of the cue stick after a hit is applied with side spin on it.
This is the running score of a player during his inning of play. The sum of the continuously scored points, or where the player stands in the run on the table.
This term refers to a foul in snooker golf.
Any shot in which the cue ball or an object ball has to squeeze by (just miss with almost no margin for error) another ball or balls in order to reach its intended target.
A specific ball number followed by "out" refers to a handicap in nine-ball or other rotation games where the "spot" is all balls from that designated number to the money ball. To illustrate, the 6-out in a nine-ball game would allow the player getting weight to win by legally pocketing the 6, 7, 8 or 9 balls.
Short for run out, especially as a noun: "That was a nice out."
The ease with which a player is generating cue power, due to well-timed acceleration of the cue at the appropriate point in a shot.
A line, sometimes imaginary (especially in American pool), sometimes drawn on the cloth, that runs horizontally across the table from the second diamond (from the head rail) on one long rail to the corresponding second diamond on the other long rail. In most pool games, the opening break shot must be performed with the center (base) of the cue ball behind the head string (i.e. between the head string and head rail). The head string intersects the long string at the head spot, and delimits the kitchen (and, in European nine-ball, the outer boundary of the break box). The head string's position is always determined by the diamonds, in contrast to the similar but different baulk line, the position of which is determined by measurement from the bottom cushion (head cushion).
In snooker, where the cue ball is resting in contact with another ball. If this ball is a ball that may legally be hit, then it is allowable to simply hit away from it and it counts as having hit it in the shot. If the ball moves, then a push shot must have occurred, in which case it is a foul.
A ball that is easily made from many positions on the table but which is left untouched while the rack is played, so that in the event the player gets out of position, the shooter has an insurance shot. Typically an insurance ball will be in or near the jaws of a pocket.
A shot in which the cue ball is driven first to one or more rails, then hits an object ball and kisses back to the last rail contacted. It is a common shot in carom games, but can be applied to such an instance in any relevant cue sport.
This refers to the cluster of balls remaining in a similar position to where they were within the break
Same as foul
Three Cushion is a form of carom billiards.
The object of the game is to carom the cue ball off both object balls and contact the rail cushions at least 3 times before the last object ball. A point is scored for each successful carom.
A shooter's body position and posture during a shot.
This refers to a shot that travels on a shallower path due to the english placed on it. This is to come up on the near side of a pocket on a bank shot.
A ball hanging over the edge of a pocket.
Sometimes called a snake shot. A carom billiards shot, common in three-cushion billiards, where the cue ball is shot with reverse english at a relatively shallow angle down the rail, and spins backwards off the adjacent rail back into the first rail.
This is a series of angled rails present within some pool tables that directs pocketed balls to a central location on the table for retrieval after the game.
