the knuckle duster

A sexual act to which a man forcefully pushes his lubricated fist into the women's arsehole for her sexual pleasure. The man then brings out the fist before the women orgasms and licks the lady's rim whilst she shits onto his tounge. Better performed by ebony women due to their eating habits as they can push out more elaberat shits

I took it upon myself to perform the knuckle duster on laqisha last night, and she was less than impressed.

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
