To blup, or blupping, is the sound made when a man, having sex on top of a woman, bears down on the womans tits to the point that a blast of air escapes, emitting a strange but amazing sound.
A similar but far less sexy sound is made by cupping your hand expertly under your armpit and waving your arm about like a chicken.
