A sexual act where one person lies face down on the floor. The other person sits perpendicularly on the other person's butt. The two people then spread their cheeks, inch their buttholes as close as they can to one another, and proceed to pass gas into each other's buttholes.
I met this girl at the bar last night. But I didn't want to cheat on Susan. So we just did a Midwest Mudbomb.
