A sexual act/game that can be played with your friends who have penises. You both down a large amount of water and then you both pretend to use your penises as chopsticks and whoever pisses first loses.

The sexual act of consuming as much epicac and laxitives as the human body permits, then using your supercritical shit and vomit combo to paint your partner before rolling around, locked in coitus, writing the entirety of Mozarts 5th symphony with your body fluids.

A Golden Powerwash is you you take a shit, and then you have to take a piss. You use your piss to clean the remaining shit smears.
Damn, Jack, I had to use a Golden Powerwash to clean off the remaining shit smear, and I flushed a turd.
