Dude...Not Cool 

1# Grossly insenstive, blantant lack of consideration or forethought; social ineptitude.

2# One who is on the verge of being deemed a stark, raving asshole.

DUDE: uh, I know invited you out for dinner, but I uh...left my wallet at home.
CHICK: Can you pay me later tonight?
DUDE: uh...not all of it, I just paid rent...but at least 10 or 15 bucks...does that mean you're staying over?
CHICK: Dude...Not Cool.
