D.U.F.F. 

The Designated (/Dumb) Ugly Fat Friend.

The cock-blocking friend of the hot chick you're trying to hook up with, often the target of the wingman.

I was totally in with this chick and then her D.U.F.F. totally cock-blocked me!

-or-

I'll take her, while you distract her D.U.F.F.!

G.U. 

"geographically undesirable" - lives too far away to date conveniently

He was totally G.U.- he lived outside the beltway so it was always a huge hassle to get together.

No U^No U 

A comeback so powerful that there are five possible outcomes.
1. Nothing happens because there was no insult in the first place
2.The opponent dies because the insult was miniscule
3 You die because the insult was moderate
4. You summon armies if the dead because the burn was kinda bad.
5. God comes to intervene because the original burn was really bad
???6 A never documented result only heard in legends you become ultra instict shaggy

You stuck
NO U^NO U
