The 'Lady Jane Grey' is a rarely used term to describe a shot in the game of snooker. The cue ball is baulk side of the spotted black after potting a red ball. The black is powerfully potted into a top corner pocket and the cue ball bounces off the top cushion into the red balls, moving them into space, thus allowing the continuation of a break. Named after Lady Jane Grey, the 16th Century Queen of England, possibly because the speed the cue ball must be hit matches the speed with which she was deposed from the throne.
See two-shot carry.
To "give someone weight" is to give them a handicap so the game is more even in skill level. If one player is significantly better than the other in a game, then you can add some weight, more or less balls for someone, to even the difficulty load between each player.
Literally, a pocket, but generally used in the phrases losing hazard - potting (pocketing the cue ball off another ball - and winning hazard - using the cue ball to pot another ball - the two types of legal shots that pocket balls in games in which the term is used at all, which is very few today. The term principally survives in English billiards, in which both types of shots are point-scoring. Formerly, a large number of different games made use of the two types of hazards as point scorers or losers in various different ways (thus their suggestive names). The term ultimately derives from holes or pockets in the table to be avoided, in very early forms of billiards. While the terms are disused in pocket billiards today, their lingering effect is obvious, as the vast bulk of such games focus on making winning hazards and avoiding losing hazards (a notable exception being Russian pyramid in which both are legal shots).
In golf billiards, an area of the table (sometimes marked) that a player will be penalized for entering if their ball does not leave. Derives from the use of the term in the outdoor game of golf.

The opposite of running english, which has effects other than simply the opposites of those of reverse english.
Actual wire or string with multiple beads strung (like an abacus) used for keeping score. Points "on the wire" are a type of handicap used, where a weaker player will be given a certain number of points before the start of the game.
