Trunk Knuckle

Sticking a finger in someone's ass at least to the second knuckle of your finger of first knuckle of your thumb.

Hey, that dude really likes when his girl gives him a trunk knuckle around back while getting a blowie.

Knuckle Dip

An accidental action that occurs when butt wiping. Usually occurs when one unknowingly has clogged the toilet, wipes his arse, and accidentally touches the water with one's knuckles.

I didn't know the toilet got clogged after my courtesy flush, so when I wiped my ass, I did a knuckle dip.

Knuckle Cock

Finger fucking a guy's girl under the table at a bar while he is at the table, then punching him in the face afterwards, karate style, with two fingers, like Chuck Norris.

I knuckle cocked that douchebag and took a shot of Jack to top off the night.
