F.U.G 

Acronym for Fat Ugly Goat (or Fat Ugly Girl). A General insult, usually used against females, that can also somehow be used as a replacement for the word "fuck" in the phrase "fuck you" (althought the mechanics of it dont quite work) Also can be used to replace "bitch"

Boy 1: Dude, that girl jus kicked me because i said she had a fat ass.

Boy 2: Whatever, she's a F.U.G anyway.
