stack attack 

A sexual act typically performed with a minimum of one male and two females where the females are “stacked” one on top of the other and penetrated by the male in an alternating fashion. Generally this results in the male achieving orgasm very quickly.

Last night I was so horny that I gave Lauren and Rachael the stack attack.
