rattle snaking 

A sexual act, usually following felatio, that involves the female wrapping one or more hands loosely around the male's penis just before he climaxes and shaking them from side to side rapidly. This produces as rattling sound as the male ejaculates. A hissing noise at this point is recommended but not essential. Also some times described as making the angry rattle snake spit/puke.
