24 Random Essential Billiards Terms

A stroke in which the cue's tip glances or slips off the cue ball not effectively transferring the intended force. Usually the result is a bungled shot. Common causes include a lack of chalk on the cue tip, a poorly groomed cue tip and not stroking straight through the cue ball, e.g. because of steering.
This is a shot that shows great control and positioning in where the cue will be when all the balls stop rolling.
Same as solids, in New Zealand. Compare little, small, reds, low, spots, dots; contrast overs.
This is to use running english or soft speed in order to open up the angle on a particular bank shot.
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.

In snooker, the abandonment of a frame upon agreement between the players, so that the balls can be set up again and the frame restarted with no change to the score since the last completed frame.

Also nurse shot, nursery shot. In carom games such as straight rail, balkline and cushion caroms, where all the balls are kept near each other and a cushion, and with very soft shots, can be "nursed" down a rail on multiple successful shots that effectively replicate the same ball setup so that the nurse shot can be repeated again (and again, etc.). Excessive use of nurse shots by players skilled enough to set them up and pull them off repeatedly at will is what led to the development of the balkline carom billiards game variations, and repetitive shot limitation rules in English billiards. A clear example of why: In 1907, Tom Reece scored a record break of 499,135 consecutive points over a period of five weeks, without a miss, using the cradle cannon nurse shot.
