The Donkey Punch is when your engaged in anal sex and when your about to ejaculate you punch the poor little lady in the back of the head so her anal cavity tightens making the orgasm all that more better (for you ofcourse). The Donkey Bobsleigh is when you do this at the top of a flight of stairs and straight after the punch you ride her down the stairs like a bobsleigh!
