Definition of One on one

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

This is a player who has the ability to make difficult shots in one pocket, because they are likely proficient at other pool games first.

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

A multi-game division of a match, as used in some league and tournament formats. For example, in a match between 2 teams of 5 players each, a 25-game match might be divided into 5 rounds of 5 games each, in which the roster of one team moves one line down at the beginning of each round, such that by the end of the match every player on team A has played every player on team B in round robin fashion.
A level of competition elimination in a tournament, such as the quarterfinal round, semifinal round and final round.

Short for top spin, i.e. same as follow.
Chiefly British: The half of the table in which the object balls are racked (in games in which racked balls are used). This usage is conceptually opposite that in North America, where this end of the table is called the foot. In snooker, this is where the reds are racked, nearest the black spot; this is the area in which most of the game is usually played.
Chiefly American: Exactly the opposite of the above - the head end of the table. No longer in common usage.

Nickname for the nine ball, usually only used when playing the game 9-Ball.

Also treble. A British term for a type of bank shot in which the object ball is potted off two cushions, especially by sending it twice across the table and into a side pocket. Also called a two-cushion double.

Chiefly British: Short for side spin. In Canadian usage, the term is sometimes used as a verb, "to side".

This refers to the cluster of balls remaining in a similar position to where they were within the break.

This is a method of handicapping that designates a wild ball for a lesser player to be able to pocket at any point during a game in order to win.

The triangular device, generally plastic, used to group the balls in a pyramid form prior to the beginning of a game.

An unintentional and often barely perceptible curve imparted to the path of the cue ball from the use of english without a level cue. Not to be confused with a swerve shot.

A type of rest, with a straight shaft and "x"-shaped head for resting the cue upon.

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."

In snooker, a shot where a player fouls by missing the ball on altogether. The miss rule allows for his opponent to have the player play exactly the same shot again, or at least as accurately as the referee is able to reproduce the ball positions. A miss usually occurs when a player makes an unsuccessful attempt at escaping from a snooker. It is a controversial rule aimed at formally discouraging deliberate fouls. In professional snooker, a referee will almost always call a miss on any foul where the player misses the ball on altogether, regardless of how close the player comes to hitting it, however no miss can be called when either of the players requires snookers to win the frame. If a player is called for a miss three times in a single visit while not snookered, he forfeits the frame; to avoid this, players almost always play an easy hit on their third attempt, even if it is likely to leave a chance for the opponent.

A pocket; usually used in disgust when describing a scratch (e.g., "the cue ball's gone down the sewer").

A natural is an easy shot requiring no side spin. A shot is said to be natural if it does not require adjustments, such as a cut angle, side spin, or unusual force. A natural bank shot, for example, is one in which simply shooting straight into the object ball at medium speed and with no spin will send the object ball directly into the target pocket on the other side of the table.

See two-shot carry.

A slang term for a cue, usually used with "piece", as in "that's a nice piece of wood".

This is the way a ball rolls when impeded by something on the table or a blemish in the cloth, often times regular players will remember certain rolls and play to them.

The break box is a zone in the "kitchen" of the head (British: bottom) of the table, from which the break shot must be taken with the cue ball,

Same as spot

This is the portion of the butt of your cue just below the handle or wrap. This portion of the cue is made separately and often times cored out to ensure the proper weight balance within the full length of the cue. This portion of the cue is usually made with exotic wood that matches the wood in the forearm or in the points on the forearm. This section is used to highlight the design of the forearm, sometimes a re-creation, a reverse, or a rendition of the same pattern on a smaller scale.

A common way to keep track of games won when playing for small money is to use a coin that is placed under the rail next to the diamonds on the rail. The center diamond at the head of the table is taken as zero, and each diamond from that is considered to be one game. To go 'around the world' is to beat your opponent so badly that the coin travels all the way around the diamonds on the table.
