Definition of Low balls

In the game 9 Ball, making the nine ball early with a legal shot, but not on the break.

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.

When a ball goes into a pocket then pops back out. It really is not witchcraft, but is usually because the pocketed ball was traveling to fast and either ricocheted off the back or sides of the pocket opening. Sometimes,on tables with plastic inserts, the object ball can bounce out from the bottom of the pocket.

A pejorative term for an improper rack in which the balls are not properly in contact with their neighbors, often resulting in a poor spread on the break.

Also shortstop, short-stop. This is a player that is excellent at pool, but tends to fall short of number one. A shortstop is the best player relative to a particular scene. A second-tier professional who is not (yet) ready for World Championship competition. It can also be applied by extension to a player who is one of the best in a region but not quite good enough to consistently beat serious road players and tournament pros. The term was borrowed from baseball.

A pool cue designed for breaking. Along with sometimes having unusual weight or balance to build maximum speed for the cue ball, some break cues have stiffer shafts and special breaking cue tips to transfer energy more efficiently to the cue ball.

A British term describing when a ball is tight on the cushion and a player sends the cue ball to hit both the object ball and the rail at nearly the same time; the object ball, ideally, stays tight to the rail and is thus "velcroed" to the rail. Inside english is often employed to achieve this effect, hitting slightly before the ball. The movement of a ball just next to the rail (but not the shot described to achieve this movement) is called hugging the rail in both the UK and the US.

Principally British: In snooker, if a player wins a match without the need for the final session to be played (for example, if a player wins a best-of-25-frames match split into three sessions - two sessions of eight frames and one of nine - by a margin of say, 13 frames to 3), then they are said to have won the match "with a session to spare".

During a set if the opponent does not win a single game, they are said to have been skunked.

The inside walls of a pocket billiards table's pockets.

In blackball, a situation where the player cannot see any of the balls she/he wants to hit due to obstruction by other balls or the knuckle of a pocket. The player must call "total snooker" to the referee, which allows a dispensation to the player from having to hit a cushion after contacting the object ball, which is otherwise a foul.

A joint type which makes it possible to screw and unscrew the butt and shaft very quickly; faster than standard threads.

Chiefly British: Same as duck, and stemming from the same obvious etymology.

This is a timing device for monitoring and restricting shot times for a player.

This is a certain type of system used to determine who plays first in the next game. These methods are not synonymous with pool skills, and are more along the lines of flipping a coin, paper-rock-scissors, or drawing straws.

A short and loose stroke performed in a manner similar to the way one throws a dart; usually employed for a jump shot. See also nip draw.

This is an imaginary line that separates the halves of the table by crossing at the middle of the side of pockets.

Means either push out or push shot, depending on the context.

The situation arising in many pool games where a ball is spotted to the table's foot spot or some other specific location and the cue ball must be shot from the kitchen or the "D". There are diamond system aiming techniques for pocketing such shots without scratching the cue ball into a pocket.

Describing a pot played at such a pace as to just reach the pocket and drop in without hitting the back.

Also on the lemon. Disguising the level of one's ability to play.

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.

A shot in which if the target is missed, the opponent is safe or will not have a desirable shot;
A shot in which there are two ways to score;
A shot in which a second ball is targeted to be pocketed, broken out of a cluster, repositioned or some other secondary goal is also intended.

Describing a difficult pot: "the awkward cueing makes this shot missable."
