Knuckle Custard

A busted load of jizz all over your fingers after rubbing one out.

Hand me my gak towel. I need to wipe up this knuckle custard.

I apparently didn’t wipe my hands good after jacking off this morning. I still got knuckle custard on them.

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.

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.

Someone of limited intelligence and with a mean nature. Who prefers using their knuckles/fists, to using their head.
