Describes a ball rolling along a rail in contact or near contact with it, or which makes multiple successive contacts with the rail.
An illegal shot (foul) in which the cue stick's tip contacts the cue ball twice during a single stroke. Double hits often occur when a player shoots the cue ball when it is very close to an object ball or cushion, because it is difficult to move the cue stick away quickly enough after the cue ball rebounds from the cushion or object ball.
Also topspin, top-spin, top. Same as follow. Contrast bottom spin, back spin.

This is a very easy and safe shot to execute in the game of one pocket.

Hitting the object ball with too large of a cut angle; hitting the object ball too thin. It is a well-known maxim that overcutting is preferable to undercutting in many situations, as is more often leaves the table in a disadvantageous position on the miss than does an undercut. See also professional side of the pocket.
An abrasive tip tool used as a grinder to roughen the cue tip to better hold chalk after it has become hardened and smooth from repeated impacts with the cue ball. Tappers serve the same purpose, but are used differently. Similar to a shaper, but shallower and less rough.
Any mechanical aid that serves to extend the length of the player's cue, normally added to the end of the butt either by clipping around the end or screwing into the base. Though extensions are used for pool, it is more common in snooker because of the significantly larger table size.
In a tournament where players get limited time to make their shots (common in televised matches), an extension is extra time granted before making a shot; players have a limited number of extensions in each frame.
