Get the Peruvian Butt Music mug.
When a bunch of dudes stand in the middle of a circle back to back and around the edge of the circle there are women with their bare asses pointing toward cluster of dudes. The men spin in a circle while music is playing, and when the music stops the men all try to start having anal sex with one of the girls. The guy who doesn't get to a girl gets knocked out, and the last man standing wins.
"Bro, wanna get together with the gang tonight?"
"Eh, I don't know..."

"Oh, well in that case count me in!"
