knucklebuster

Adj.

Usually pertaining to butch lesbians, a knucklebuster is someone who forcefully, and rapidly inserts their fingers (usually 2-3) into a woman's vagina, and in doing so they injure the joints of said fingers. Medically speaking, it's usually a small strain in a joint, not a knuckle, but the nomenclature holds steadfast.

A derogatory reference to a lesbian, or a girl who won't put out right away

The direct result of hardcore "fingerbanging"

Dude A: Did you hook up with that girl?
Bummed Dude: No, she was a goddamned knucklebuster

Knuckledusting

When a loved one or significant other won't help a bro out and he's forced to knuckle his own junk. Said bro shoots baby batter into his own hand and allows it to dry. The following morning punches the unwillingly participant from the night before creating an eruption of cum dust shooting from his knuckles.

Liz wouldn't go down on mike, so he gave her a full-on knuckledusting the next morning.

knucklebug

An odd mysterious bug that you only see on your knuckle and no where else. You then interrupt your friend’s conversation about some bomb ass booty they saw in the gym, telling them about some bug on your knuckle.

Hey! Did ya’ll see that knucklebug on me?
