A fart. So named because beans make excellent fart fuel and cause many of the farts we smell.
I was alone in the elevator, so I decided to drop one super stinky bean bomb right then and there, so I would not offend anyone nor embarrass myself. Right then, the elevator stopped, and that super foxy chick I've been wanting to ask out appeared as the door slid open. She smiled invitingly. Then the looks of suprise, repulsion and disgust quickly washed across her face. "GROSS!", she yelled, as she turned around and jogged towards the elevator down the hall.
