rusty fucknuckle

typically the second knuckle of your ring finger after finger fucking a womans tight puss with your pointer and middle fingers only; results from getting poo from her rectum hole on it

Celeste is great. First she slobbed my knob and gobbled the baby gravy then she licked my rusty fucknuckle clean of her week old ass mayo/ fudge stank combo. AND, I posted it on Youtube for all to see.

fucknuckle 

a wanker, an idiot, a jack-off. technically someone who fucks their knuckle, i.e. their hand.

instead of calling someone "fuckin' wanker" or "jack-off", you might call them "fucknuckle" - quite offensive.
