Mungadungus 

1.The stuff your grandmother picks out of her toenail.

2.The stuff that comes out of zits.
3. Any disgusting bodily pus or infection

After getting a pedicure, the beautician wiped all off the foot mungadungus onto a kleenex, cringed in disgust, then threw it away.

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.

Mundungus 

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!
