fuck knuckle

Someone who is a complete and utter idiot.

1. Don't be such a fuck knuckle.
2. That fuck knuckle crossed the highway without looking.
3. If you're going to be a fuck knuckle, you can piss off.

Knuckle panini

Just like a knuckle sandwich but the hand has to be extra warm and sweaty

Person 1: damn!! You really gave him a taste of your knuckle sandwich!

Person 2: Eh.. it was more of a knuckle panini just because how anxious I was.

Fuck Knuckle

A man with such a small dick that all it feels like when he fucks a woman is him fucking her with the knuckle on his fist.

HER: Enough playing around stick it in already
HIM: What you talking about Willis? It is in!
HER: I should have known you'd be a fuck knuckle.

five knuckle sandwich

hands used in barehanded boxing aka fisticuffs

So, the gloves went off and we engaged in fisticuffs feeding ourselves five knuckle sandwiches until one of us saw stars
After the argument I just fed him a five knuckle sandwich

Knuckle buster

While in spoon position with your partner, you put your pinky in the Booty hole, ring and middle fingers in the vagina, and use your pointer finger to stimulate the clitoris.

Whether my wife is being naughty or nice, I always end the night with a knuckle buster.
