Dragonball Z

When two people touch assholes and try to shit into each other’s asses, imitating the clash between blasts that happen between Dragonball Z characters. Instead of getting injured or blown away when they lose, the loser’s asshole must swallow the winner’s sewer pickle in full.

“Hey man, wanna come over my house and Dragonball Z in the bathroom?”
“Sounds gay, I’m in.”
