Fucknuckle

An idiot who digs (looks) into things that should not be dug (looked) into, only to find out they're wrong about why they went in search and also in what they found.

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 person, often a jockey at a picnic race meeting, say Bong Bong for instance, who, in the process of winning the first race is also charged with careless riding and receives a lengthy suspension, is also caught by the Stewards using their mobile phone on-course, then injures their toe during the final race on the card and lastly fails to ride their mount out to the post. They are definitely a fucknuckle of the highest order.
What a fucknuckle that bloody useless picnic jockey was at Bong Bong last Friday.
