The act of two people facing each other and watching each other masterbate at the same time.

"Since we can't have intercourse, shall we partake in nexterbation?"

Nusterbation 

When you rap your nuts around your buddy's cock and jack them off with your sack.

Note* If your buddy spunks on your sack, it means your totally gay.

I Nusterbated my buddy off and he jizzed all over my wiener. After he licked the jizz off he said, "Wow, Nusterbation is awesome!"
