Partners with lots of history!!

I work with a guy like this. Every shift I have with him he's telling us about some new chick he's banging, and how naaaasty she is. How baaaad she is. How aaaaawesome he is.

He's full of shit, just like your friend. Either that or, from the way you tell it, he's an unsavory sort of character, far from through with his evil ways. The two of you need to be disillusioned from the idea that going through people like they're fruit snacks is something to be impressed by. I'm an echo, but run for the hills girl.

Edit: Remember, Grease is a story. Don't expect your Zucko to join the baseball team for you.

Jam it back in, in the dark.
