When you take a shit on a public restroom floor. similar to that of doing the "helicopter" but going number 2 instead of 1. normally the center of the room is ideal so that everyone coming into the bathroom can witness your raid on terror. or you can go for the silent approach and drop it in the stall leaving a pleasant suprise
bro 1: dude i just did a helicopter in the ampm bathroom
bro 2: fuck ya bro ill go finish it up with a carpet bomb!
bro 1: hahaha!
bro 2: hahaha!
