Stack and Jack 

This is when no less than 9 homeless guys pile into the back seat of your car (generally a Prius) then lay down on top of each other stacking one by one then jack each other off.

Hey Lou! That there fuck party we had behind the dumpster last week damn near broke my dick off! Maybe tonight when everyone gets here we can just jump in this Prius and do an old fashioned Stack and Jack...So we can have a night off and I can ice my dick...
