24 Random Essential Billiards Terms

When the tip of the cue begins to hang over the sides of the ferrule from constant use. This is the action of mushrooming, and it is important to use a tip tool to reshape the tip to fit the ferrule.
This refers to the cluster of balls remaining in a similar position to where they were within the break.
A tactic employed in UK eight-ball pool in which a player calls and pots one of the balls in a favorably lying set, then plays safe, leaving as many of his/her well-placed balls on the table as possible, until the opponents commits a foul or leaves a chance that the player feels warrants an attempt at running out.

A Baulk line is line drawn across the table 29 inches from the bottom cushion and parallel to that cushion.
A situation in which a ball strikes another ball which is close to a rail and the struck ball rebounds back into the ball it was hit by; usually but not always unintended.
To move a ball (usually deliberately) from a safe position, e.g. close to the middle of a cushion or in a cluster, so that it becomes pottable.
Describes tightly woven and well-used (but clean) billiard table cloth (baize), upon which the balls move quickly and roll farther, as they experience less friction than with fuzzy or dirty cloth. May be used more extendedly, as in "this is a really fast table". Fast cloth makes draw (screw) shots somewhat less effective, as there is less purchase for the cue ball's back spin. By the same token, slide and stop shots are easier on fast cloth because it is so comparatively smooth.
The point on the table surface over which the apex ball of a rack is centered (in most games). It is the point half the distance between the long rails' second diamonds from the end of the racking end of the table. The foot spot is the intersection of the foot string and the long string, and is typically marked with a cloth or paper decal on pool tables.

Many league players also use cheap but solid sneaky petes as their break cues.
Same as position. "She got good shape for the next shot". See also position play, leave.
Playing an opponent for money who has no chance of winning based on disparity of skill levels. The term robbed is also sometimes used humorously in exclamations when a shot that looks like it would work did not, as in "Oh! You got robbed on that one!"
Accidentally causing the cue ball or any object ball to leave the table. It is normally a foul.
This is a shot where the cue ball follows directly behind the sunk object ball into the pocket right after it falls.
A 7 inch (17.8 cm) square box drawn on a balkline table from the termination of a balkline with the rail, thus defining a restricted space in which only 3 points may be scored before one ball must be driven from the area. It developed to curtail the effectiveness of the chuck nurse, which in turn had been invented to thwart the effectiveness of the Parker's box in stopping long, repetitive runs using the anchor nurse.
Refers to a person gambling when he has no money. As in, "That jerk can't pay up, he was shooting air barrels the whole time".
Any shot that intentionally accounts for the elasticity of the cushions to allow a ball to bank past an otherwise blocking ball. The moving ball will sink in to the cushion very near the blocking ball giving it sufficient space to get past it or kiss off the back side of it.
