elevator popcorn
When you let out a long, silent fart in a crowded elevator. You wait until the elevator door closes and then say, "Hey, does anyone smell popcorn?" You smile as you hear everyone in the elevator inhale through their nostrils in unison.
Goofy: "Hey, Mick-- Garsh, what's so funny?"
Mickey: "Huh, huh! I was riding in an elevator full of people and served up some hot, Elevator Popcorn!"
