Russian Trampoline 

A sex game in which the 'server' inserts an ice cube into their asshole and then forcefully expels the projectile directly into their partner's mouth. The partner then returns fire, shooting the ice cube out of their mouth and back into the asshole. This back and forth volley continues until there is an unsuccessful ice cube reception, uncatchable pass, or the ice cube simply melts to the point it becomes unusable.

Made famous by the 2014 Sochi Olympic Village.

Guy 1: "Man, I came home last night and caught my roommate and his friend playing the damn Russian Trampoline again. I'm getting sick of this shit! There's never any ice left in the tray when I get home!"

Guy 2: "Don't knock it till you've tried it bro."
