Definition of Stick your rock

To reach a certain position in a tournament. "I placed 17th." "She will probably place in the money this time."

The pocket in snooker that is closest to the green spot.

To apply chalk to the tip of your cue before a shot.

Describes the propensity of pockets to more easily accept an imperfectly aimed ball shot at a relatively soft speed, that might not fall if shot with more velocity ("that ball normally wouldn't fall but he hit it at pocket speed"). The less sensitive to shot-speed that a pocket is, the "faster" it is said to be.
Describes the velocity of an object ball shot with just enough speed to reach the intended pocket and drop. "Shoot this with pocket speed only, so you don't send the cue ball too far up-table."

The ornamentation on a cue is often made by inlaying exotic materials into the wood of the butt portion of the cue. Inlays of ebony and ivory are quite common. The value of a cue is often based on the number inlays.

A British term for a pot that requires very fine contact between cue ball and object ball. See also feather.

Literally, a pocket, but generally used in the phrases losing hazard - potting (pocketing the cue ball off another ball - and winning hazard - using the cue ball to pot another ball - the two types of legal shots that pocket balls in games in which the term is used at all, which is very few today. The term principally survives in English billiards, in which both types of shots are point-scoring. Formerly, a large number of different games made use of the two types of hazards as point scorers or losers in various different ways (thus their suggestive names). The term ultimately derives from holes or pockets in the table to be avoided, in very early forms of billiards. While the terms are disused in pocket billiards today, their lingering effect is obvious, as the vast bulk of such games focus on making winning hazards and avoiding losing hazards (a notable exception being Russian pyramid in which both are legal shots).
In golf billiards, an area of the table (sometimes marked) that a player will be penalized for entering if their ball does not leave. Derives from the use of the term in the outdoor game of golf.

A situation where the cue ball is directly in front of another ball in the line of the shot such that the player is hampered by it, having to bridge over it awkwardly with the likelihood of a foul looming if the object ball is inadvertently touched.

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.

A set of paired balls in the game of cribbage pool that have a number value which combined equal 15. For example, the 8 ball and the 7 ball added together equal 15 and thus constitute one cribbage if pocketed in succession.

When the cue ball contacts three or more cushions in carom games.

In eight-ball and related games, describes the situation in which neither player has yet claimed a suit (group) of balls. Often shortened to simply open: "Is it still an open table?" "Yes, it's open."

This describes a player who is not particular good at completing long shots. They may have other skills that help them in the game of one pocket pool, but when faced with long shots; their execution is less than perfect.

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.

A player who was not shooting well during a match but suddenly turns it around and starts playing better and more accurately. Also known as "Finding a stroke" or "Found their stroke".

This is the act of disturbing you opponents good looking balls in the hope that they might move over and help you out in the game of one pocket.

The precise center of the pool table.

Any mechanical aid that serves to extend the length of the player's cue, normally added to the end of the butt either by clipping around the end or screwing into the base. Though extensions are used for pool, it is more common in snooker because of the significantly larger table size.
In a tournament where players get limited time to make their shots (common in televised matches), an extension is extra time granted before making a shot; players have a limited number of extensions in each frame.

White talcum powder placed on a player's bridge hand to reduce moisture so that a cue's shaft can slide more easily. It is not provided in many establishments as many recreational players will use far more than is necessary and transfer it all over the table's surface. Venues that do provide it usually do so in the form of compress cones about 6-inches tall. Some serious players bring their own, in a bottle or a porous bag that can be patted on the bridge hand. Many players prefer a pool glove. Talc is frequently mistakenly referred to as "hand chalk", despite not being made of chalk.

A bridge formed by the hand where no finger loops over the shaft of the cue. Typically, the cue stick is channeled by a "v"-shaped groove formed by the thumb and the base of the index finger.

The act of playing a devastating safety which leaves the opponent in a situation where it is very difficult or near impossible to make a legal hit on an object ball

This is missing the fact that you owe a ball in a game of one pocket after a scratch.

The ball meant to be struck and sunk in your called shot.

When a ball is in firm contact with a cushion or another ball.
