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.

Knuckle Chicken 

A game where two people’s hands are held in a fist bump position. It’s similar to the game ‘Slapsies’. It’s the same consept but it hurts a lot more.

You try to hit the other person’s hand with your knuckles, if you miss, it’s their turn.

If you chicken out, in other words, stop the game, you lose. It’s more fun if there’s something on the line.

“Wanna play Knuckle Chicken? I won’t break your hand like last time.”
