The three-foul rule describes a situation in which a player is assessed a defined penalty after committing a third successive foul. The exact penalty, its prerequisites and whether it is in place at all, vary depending on the games. In nine-ball and straight pool, a player must be the told he is on two fouls in order to transgress the rule, and if violated, results in a loss of game for the former and a special point penalty of a loss of fifteen points (plus one for the foul itself) in the latter together with the ability to require the violator to rerack and rebreak. In Irish standard pool and English billiards, it is a loss of game if a player commits a third foul while shooting at the black. In snooker, three successive fouls from an unsnookered position result in forfeiting the frame. Repeat fouls from a snookered position are quite common - Dave Harold holds the record in a competitive match, missing the same shot 14 successive times.

This a shot that hits the object ball at the nine ball to see if you can get lucky by sinking the nine ball in any pocket. (also see Rolling the Cheese and Cheese the Nine).

Also double-century break. In English billiards, a break of 200-299 points (i.e. double a century). Larger multi-centuries are regularly achieved. Rare in amateur play, triple centuries are routine, and quadruples not uncommon at World Professional Billiards Championships; 2007 winner Mike Russell shot four triples in the final round alone, while of sixteen competitors, three shot quadruple centuries (one once, one twice, and Russell three times). Quintuple centuries are rare even at the professional level, with only the 494 shot by nine-time World Champion Russell (who has more such titles than any other player in history as of 2007) coming close in that event. World Champion Geet Sethi holds the world record, at a duodectuple century (and then some) of 1276 consecutive points."

Any system for banking or kicking balls multiple rails which uses table diamonds as aiming references.

When the cue ball is tucked behind the corner of a pocket or behind other object balls against a rail, therefore not allowing a direct shot at the object ball without the cue bouncing off the corner of the rail.
A term also used to mean when the object ball you must hit next is hidden behind other balls against a rail and you are not able to get a clean hit (without hitting other object balls first) on it. e.g. "You hooked me".

In snooker, where the cue ball is resting in contact with another ball. If this ball is a ball that may legally be hit, then it is allowable to simply hit away from it and it counts as having hit it in the shot. If the ball moves, then a push shot must have occurred, in which case it is a foul.

A specific ball number followed by "out" refers to a handicap in nine-ball or other rotation games where the "spot" is all balls from that designated number to the money ball. To illustrate, the 6-out in a nine-ball game would allow the player getting weight to win by legally pocketing the 6, 7, 8 or 9 balls.
Short for run out, especially as a noun: "That was a nice out."

The inside walls of a pocket billiards table's pockets.

The tip of your cue is the smallest but most important piece on all of the stick. Ranging between 12 mm and 14 mm depending on the taper of you shaft, the average and most common tip size is 13 mm. The tip is usually made from treated and compressed leather and is attached at the top of your cue by screw or glue to the ferrule. There are variances in cue tip resistance from soft to hard. The softer offering more chalk retention, and the harder offering more longevity and power transferred through your shot (the hardest, phenolic tips are often used on the break). Because the surface of the tip is beveled it offers you control on the spin and direction of the cue ball in your shot. To keep this control, it is important to scuff up the surface of your cue a little so as to enhance the chalk retention potential. In addition to keeping you tip chalked, you want avoid it mushrooming over the ends of the ferrule after too many impacts without refinement. To much use, and not enough care with proper tools can hinder your ability to master the control from your cue tip to your shot.

To fail to make a legal shot.

A style of game play in which as many players are allowed to join as the participants choose, and anyone can quit at any time. The term, most often used in the context of gambling, is borrowed from poker. The folk games three-ball and killer are usually played as open ring games, as is Kelly pool.
By extension, a multi-player game that anyone may initially join, but which has a fixed roster of competitors once it begins, is sometimes also called a ring game. Cutthroat is, by its nature, such a game. A famous regular ring game event of this sort is the Grady Mathews-hosted six-player, $3000-buy-in ring ten-ball competition at the annual Derby City Classic.
A nine-ball ring game is played by more than two players. Safeties are not allowed.

The ornamentation on a cue, between the wrap and the joint, is often made by inlaying exotic materials into the wood so the inlays form points. The value of a cue is often based on the number points.

Oceania Pocket Billiard Association.

The effect of shooting regulation-weight object balls with an old-fashioned over-weight bar table cue ball, such that the cue ball moves forward to occupy (sometimes only temporarily), or go beyond, the original position of the object ball, even on a draw or stop shot, because the mass of the cue ball exceeds that of the object ball. Players who understand smash-through well can use it intentionally for position play, such as to nudge other object balls nearby the target ball. Smash-through also makes it dangerous in bar pool (when equipped with such a cue ball) to pocket straight-on ducks with a stop shot instead of by cheating the pocket because of the likelihood of scratching the cue ball.
