24 Random Essential Billiards Terms

A player who was playing very well but suddenly starts playing badly. e.g. "He was making everything on every shot, then lost his stroke and couldn't hit anything, costing him the match."
Used in snooker in reference to the position of the cue ball. It is above the object ball if it is off-straight on the baulk cushion side of the imaginary line for a straight pot (e.g. "he'll want to finish above the blue in order to go into the pink and reds"). It is also common to use the term high instead.
In snooker and British pool, the successful potting of all object balls-on in a single frame.
This is a timing device for monitoring and restricting shot times for a player.
A tight, Spandex glove covering usually most or all of the thumb, index finger and middle finger, worn on the bridge hand as a more convenient and less messy alternative to using hand talc, and for the same purpose: a smooth-gliding stroke.
In snooker, to leave the cue ball ball on the spot of a colour ball after potting it. This is usually performed where re-spotting of the colour ball would cause positional problems for the player, such as blocking available pots on one or more red balls.
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.
This is a particular ball which lends itself to be used as a "blocker" or a "protector."
To use a particular ball as security by playing a safety or leaving it where it will act as one.

A pool table spread in which the balls are extremely easily positioned for a run out, and where little movement of the cue ball on each shot is necessary to obtain position on the next.
Powdered chalk housed in a cube. This chalk is rubbed into the tip of your cue to help with grip between the tip of the cue and the cue ball. This is more important to use if you are using a medium or hard tip, as opposed to a soft tip, which already provides some good grip. As a warning when purchasing a type of chalk, there is much debate over which chalk offers the best friction, so you best do your research!
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.
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.
This describes when a player is trapped behind a ball. (n.) - This is also the amount of money a player is down after betting.
This is a term used more in snooker to refer to a follow shot, when the cue ball is hit above center to allow it to follow the object ball after impact.
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.
