24 Random Essential Billiards Terms

0-2 Barbecue is a slang billiard term that refers to a single player loosing the first 2 matches in a double elimination tournament. This double loss results in that player being knocked out of the tournament without winning even one game.
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!
On a shot, the extension of the cue stick through the cue ball position during the end of a player's stroke in the direction originally aimed.
Named after Chicagoan J. E. Parker, it is a 3½ × 7 inch box drawn on a balkline table from the termination of a balkline with the cushion, thus defining a restricted space in which only a set number of points may be scored before one ball must be driven from the area. Now supplanted by anchor spaces, it was developed to curtail the effectiveness of the anchor nurse, which in turn had been invented to exploit a loophole in balkline rules: so long as both object balls straddled a balkline, there was no restriction on counts, as each ball lay in a separate balk space.
This is the point on the object ball where the cue exactly impacts or the point at which two balls touch when they impact.
Any standard pool cue used to shoot the majority of shots in a match.
To sink a ball into a pocket.

This is a blemish added to the table in order to help execute a shot; these marks are not allowed and result in a foul.
A form of doubles play in which the two team members take turns, playing alternating shots during an inning (i.e. each team's inning consists of two players' alternating visits, each of one shot only, until that team's inning ends, and the next team begins their alternating-shot turn.) Effective scotch doubles play requires close communication between team partners, especially as to desired cue ball position for the incoming player. Like "english", "scotch" is usually not capitalized in this context. The term is also used in bowling, and may have originated there.
This describes a shot where you bank the object ball off of a rail and then sink it in a corner pocket.
When the object ball lies behind another ball which makes it impossible to be struck by the cue with a direct hit.

This is a term to describe 100 break points in a game of snooker.
Descriptive of any game in which the object balls must be struck in numerical order. Billiard researcher Mike Shamos observes that it would be more intuitive to call such games "'series' or 'sequence'". The term actually derives from the set-up of the game Chicago, in which the balls are not racked, but placed numerically around the table along the cushions (and must to be shot in ascending order). Other common rotation games include pool (obviously), nine-ball, seven-ball, ten-ball.
The act of setting up the balls for a break shot. In tournament play this will be done by the referee, but in lower-level play, players either rack for themselves or for each other depending on convention.
This is to watch a match with such intensity that there is worry, usually because of a wager on the game.

2- Verb: To perform some act or make some utterance with the intent to distract, irritate or intimidate the opponent so that they do not perform well, miss a shot, etc. Most league and tournament rules forbid blatant sharking, as a form of unsportsmanlike conduct, but it is very common in bar pool.
Noun: Another term for hustler.
Noun: A very good player. This usage is common among non-players who often intend it as a compliment and are not aware of its derogatory senses .

In certain carom billiards games, any shot in which the cue ball is sucessfully caromed off an object ball to strike another object ball (with or without contacting cushions in the interim) is a considered a billiards shot.
This is what happens when a player sends the cue ball into a cluster of balls that will in turn spread out in an unpredictable fashion.
The intersection of the head string and long string, which is usually not marked on a table with a spot decal, unlike the foot spot, though some pool halls mark both spots so that racking can be done at either end of the table, and wear on the cloth from racking and breaking is more evenly distributed.
This is a ball that is left in a position that allows an easy shot, while time is spent working with other balls to better your position in the game.
A player of cue sports.
