24 Random Essential Billiards Terms

In snooker, a situation where the scores are tied after all the balls have been potted, and the black ball is re-spotted and the first player to pot it wins. The players toss for the first shot, which must be taken with the cue ball in the D. A safety battle typically ensues, until an error allows a player to pot the black, or a fluke or a difficult pot is made.
Any shot where the cue ball stops immediately after hitting an object ball. Generally requires a full hit.
A player's (or doubles team's) turn at the table, usually ending with a failure to score a point or to pocket a ball, depending on the game, a foul, a safety or with a win. In some games, such as five-pins and killer, a player's inning is always limited to one shot, regardless of the intent and result of the shot. Usually synonymous with visit, except in scotch doubles format. The term is sometimes used to mean both players'/teams' visits combined, e.g. when referring to which inning in which a memorable shot occurred.
Same as follow (top spin).
Also Gentleman's call. An informal approach to the "call-everything" variation of call-shot, common in bar pool. Obvious shots, such as a straight-on or near-straight shot for which the shooter is clearly aiming and which could not be mistaken for another shot, need not be called. Bank shots, kicks, caroms and combinations are usually less obvious and generally must be called, though this may depend upon the mutual skill level and shot selection perception of the players. An opponent has the right to ask what the shooter's intention is, if this is unclear.

A highly abrasive tip tool used to shape an unreasonably flat new cue tip, or misshapen old one, into a more usable, consistently curved profile, most commonly the curvature of a nickel or dime (or equivalently sized non-US/Canadian coin) for larger and smaller pool tips, respectively. Similar to a scuffer, but deeper and rougher.
A rack in the form of an equilateral triangle. There are different sizes of triangles for racking different games (which use different ball sizes and numbers of balls), including the fifteen ball racks for snooker and various pool games such as eight-ball and blackball. A larger triangle is used for the twenty-one ball rack for baseball pocket billiards). The smallest triangle rack is employed in three-ball (see illustration at that article) but is not strictly necessary, as the front of a larger rack can be used, or the balls can be arranged by hand.
