knuckle spider

A knuckle spider is the act of rapidly using your fingers in a spider-like motion while simultaneously inserting your fingers inside a woman's vagina with the intent of granting her intense pleasure.

Friend: "Yo, what did you get on the test?"
Guy: "A+"
Friend: "WTF? How? I thought you said you bombed it?"
Guy: "Yeah, I really needed that A so I went in after class and gave our teacher the ol' knuckle spider" (makes spider-like hand gesture)

Knuckle popping the ham door 

Foreplay using your fingers to pleasure a female vagina

I was with my girl last night, knuckle popping the ham door & my Ma walked in.

Knuckle chunk

knuckle-dusters 

Melee weapon consisting of a piece of brass cast in a shape similar to four soldered rings through which you introduce your fingers. It also has a handle, so that you can grab it properly and use it to punch someone.

Of course, you begin the game unarmed and will actually spend a considerable length of time fighting either unarmed or with hand-to-hand weapons, including various shivs, knuckle-dusters, and clubs.
