Knuckle One

To masturbate. Jack off. Rub one out.

Roger was late to class because he stopped at the bathroom to knuckle one.

I had to knuckle one to your mom last night.

When you're wearing a thong, and your balls are so saggy that each ball falls onto both sides of the thong creating newton ball like balls, and you have someone put their tongue in between both balls, and swing the balls together like newton balls. :)

A combination if a knuckle head and dumb bunny.

Monkey Knuckle

When fisting someone's anus, and you pull your fist out covered in poop.

I can't believe they didn't clean themselves enough to prevent me from getting monkey knuckles.
