knuckle sammich 

n. Phonetic/slang version of the term knuckle sandwich. Often used to make the speaker sound cool, as to enunciate "sand-wich" often takes away from the overall badassery of a threat involving the knuckle sammich.

Give me a hug before I give you a knuckle sammich.
Go make me a sammich, woman, before I give you a *knuckle* sammich!
Damn, that cat just gave me a knuckle sammich.

knuckle balling 

To fuck a chick with a big pussy. A normal sized pussy is called a camel toe. A pussy with large outer lips is called moose knuckles. Therefore, when you fuck a chick with moose knuckles, your balls slap her enormus lips. So your knuckle balling.

Dude, I hooked up with this hot chick last night but when the panties came off she had the biggest pussy lips I've ever seen. So, did you bolt? I thought about it, but I went knuckle balling instead.
