Stink Knuckle

Yet another fine euphemism for the vagina.

I wouldn't fuck her stink knuckle with YOUR dick and blame it on Hugh Grant.

Stinky Knuckles

A game where the winner is established by how many fingers they can fit knuckle deep in another person's rear.

(In party setting)
Man 1: "Who's trying to catch a game of Stinky Knuckles"?
Man 2: "I'm down! I haven't lost a game yet"

Sink a Knuckle

To finger a girl, especially in a public setting like a movie.

The male equivalent of giving a handjob.

I've only been out with this chick twice, and she already let me sink a knuckle!
