Butt Munch-
1. An annoying person that you would like to shut up.
2. A bothersome sibling.
3. A friend who is being a jackass.

Person 1: Hey man, you sure are cool! you have so many friends! I guess that's why everyone thinks you're such a winner

Person 2: Shut up you freaking butt munch.

When you're sitting in class and the need to fart overcomes your self control so the gas is expelled through the anus. when expelled you try to stop it with a quick pinch of the anus thus creating a high pitched noise (similar to that of a trumpet) only to be blamed on the asian sitting closest to you.

"Dude, I totally buttpinched in history and blamed xing xing."
