In pocket billiards (pool), a "crutch" is the stick used to shoot with when you cannot reach the cue ball. It is formally known as a "mechanical bridge".
It's referred to as a crutch to insinuate that you're a lesser player that needs "help" to make a shot (this is a very big misconception, however).
It is sometimes also referred to as a "wussy stick".
1. to hide an item, usually a "load" of drugs in your crotch, either in your underwear or by "plugging" inside the vagina or anus.
2. to shoplift by place items up your skirt.
Used to describe a well defined vagina and pubic bone of females wearing especially tight fitting clothing around their pelvis; i.e. Lycra (Spandex) shorts, gym kit; jeans, bikini and underwear.
The best examples are when the inner thighs don’t touch below the crutch leaving a nice air gap and allowing for visual examination of the genital area.
