The pulling back of a mans excess cock skin to make the male genitalia seem larger or longer, in some cases more dagger like.
John: Rambo hit that goose knuckle pretty hard
Jim:yea his cock is elite and looks like a dagger, how appealing!!
John: yea he has a nice cock, all thanks to that goose knuckle

A halve-erect penis. When your halve hard, and halve soft it equals a knuckle, referring to your finger knuckle when bent.

Guy-He/she has a knuckles haircut, like knuckles the echidna from sonic the hedgehog.
Other guy-Man shut the fuck up, you get online and say shit about somebody, why don't you tell them about their knuckles hair?
Guy- I'm fuckin scared of him/her, why do you think I don't say nothing except online man? I'm fuckin scared to say the shit I say online in real life, I'm too embarrassed to do anything, fuck.
Other guy- Yea, you a fuckin racist hater, I knew it, you fuckin bitch.
Guy- Don't tell anybody I'd be too embarrassed.

Imagine 2 people playing Darts for the same team of 4 players. One team mate scores 180 points with 3 Darts (taking the game, because their team needed to score 180 points to win the game)
Player 1: Holy Crap, 180!!
Teammate: Dude, gimme knuckles!!!
The winning team's 4 members all bump fists.
