I tried everything to unclog that toilet. Finally had a plumber come out....he gave it the Cleveland Knuckler and she's flushing like a champ now.

Extremely fat girl whose vagina has collapsed in on itself from all the weight. Thus, fingering ends at the male's first knuckle.
I tried to finger fat Lisa the other night, but it wasn't workin out. She's either a one knuckler or 12.

This is horrible abuse to do to a person. You rub your knuckle against either your own, your victim's, or a third parties butthole then proceed to rub your "dirty knuckle" against your victim's mouth.
Tiffany: "Danny, if you don't stop making fun of my nips, I'm gonna give you the dirty knuckler!"
Danny: "NAY!"
Danny: "NAY!"

When a handjob is so constricting that the white's of the person performing the jobs knuckles are visible.
Yo meng, I went out to dinner with this body building chick, and when we got in the car she gave me the most hateful white-knuckler.

A women or girl who upon giving one a hand job, grabs and holds on for dear life. They grasp until their knuckles turn a faint tan or white color. In some extreme conditions, friction burns may result.

Common terminology for one who engages regularly in the act of fisting. May be used descriptively, or abusively at your own discretion. It is generally frowned upon, if assumed as a title.
Cad-flangin' dangle-hoppler! That sombanitch Carl is a damn fudge-knuckler! I figured him straight and narrow, but I guess he likes to play out back.
