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.

knuckle scrub

The act of vigorously scrubbing one's anus, usually with hot soapy water, to clean it of leftover fecal matter. It is more a practical technique than a pleasurable one, although some people find it serves the dual purpose.

The toilet paper at the resort was of poor quality so I had to hop in the shower and do a quick knuckle scrub before going to dinner.

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. :)

knuckles deep

A form of measurement used to determine the size or width of a vagina or anus, or the act of inserting fingers into said orifices. Preceded by a number which indicates how many knuckles.

---It still has not been determined if fisting someone is considered 4 or 5 knuckles deep, as the debate contiunes if the thumb counts as a knuckle

"So last night I was two knuckles deep in this chick's ass..."

"Her pussy was three knuckles deep--pretty impressive."

bush knuckle

An individual with an unusual amount of hair growing on the tops of the hands and between the knuckles of the fingers.

This phrase is used almost exlusively by nobody anywhere.

Trucker's Knuckles

Trucker's Knuckles refers to a severe case of multiple, external anal hemorrhoids that are raging and irritated and have a thrombosed clot under the skin causing a hard, painful lump appearing like the knuckles on a hand. Trucker's Knuckles often occur regularly to those individuals employed in long haul, over the road, driving professions.

Stan: Hey Frank. Are you heading on that haul from Chicago to L.A?
Frank: Yea and not looking forward to it.

Stan: Why?

Frank: I got the worst case of Trucker's Knuckles. Take a look. (Drops pants).
Stan: Holy Shit. Looks like a tiny fist down there. Better get some salve before you hit the road.
