The definition for a girl whom is extreamly beautiful and amazing, though considers herself fat and ugly which is a huge misunderstanding to the definition of the above word.
"Baby i feel so F-fugly" i no babe your the F-fugliest girl i know of.
Fugly, which is clearly defined in the other definitions, is only the beginning of a group of words which can be used to describe things. Works with any number of words. Fugly, fretarded, etc. The point is, you can make them up, as long as the word works with an f in front of it.
"Dude, her ass is like no."
"Yeah, she's so fugly"
"Well, yeah, and she's fretarded."
