When visiting a nightclub or other such dancing establishment, the act of unbuckling one's belt, loosening ones trousers and allowing them to drop to the floor, continuing to dance with them shuffling around one's ankles. Often whilst inebriated.

It's night time and a guy is standing on the side of a deserted road. Out of nowhere a car starts heading towards him. From the driver's perspective you see the lights getting larger on the person. The person then look directly at the driver, eyes wide, then just drops his pants to the ground and darts across the road so as to pass in front of the car narrowly missing being hit. It can be said that the man has just dropped trou' and bailed.

A trou who's gotten somebody into some serious trouble. This can range from consensual sex in the barracks being reported as 'rape' to escape punishment, to a respect board for making sexist remarks. Avoid these bitches at all costs.
If CDT X reports CDT Y to the respect officer for saying disparaging things about females underperforming at physical training, she is trou-ble.

A french food tradition, where you are served a shot of liquor in the middle of a long meal, to restore appetite. Often the shot is with Calvados liquor or ice cream sorbet.
