Appalachian Mundungus

Rubbing one's penis vigorously back and forth in an ass crack, while not actually inserting it in the anus. Also known as the asstric bypass.

She was on her period and her butthole smelled, so I just did the old Appalachian Mundungus.

Mujungus 

Bigger than big. Huger than huger. Larger than larger.
Created by a 3 year old.

To a 3 year old, a bass drum might appear to be mujungus.

Something you call your mates when they're doing some dumb shit and someone's already filming it.

Friend 1: *is about to do a backflip off of the roof while smashed*
Friend 2: *is filming*
You, a sane person: You absolute mundungus, get down from there!
