First heard on the tv show The Game, Ugly Girl Syndrome is when a girl is so insecure that she will do ANYTHING to please her man.
Tasha: I just know youve been with so many different women. Beautiful ones, freaky ones.
Rick: Don't tell me you have ugly girl syndrome
Tasha: Oh my god, are you saying im ugly? Im hideous, im an animal, dont look at me Rick!

Often an girl who suffers from Ugly Girl Syndrome is socially retarded. Using tactics such as being a slut she is able to attract a partner. Often she will lie and present herself in a grandiose manner in an attempt to distract a potential mate from her self perceived ugliness. Once mate has "fallin for" said UGS sufferer she will then self sabotage the relationship thus making her the perfect candidate for people not wanting a long term relationship.

When you've been deprived of social interaction and/or sexual contact with fit girls, thus ugly girls around you appear to become hotter due to your pent up sexual frustration.
Boy 1 - "Argh i'm so horny, i've been at this god forsaken camp for over 2 weeks now and I still haven't got any, I think i'm gonna make a move for Gretchen."

Boy 2 - "Jesus Christ mate, you have seen what she looks like right? You're suffering from major Ugly Girl Syndrome, you'd better go have a wank and then think about your UGS."

A condition where a girl who is considered unattractive by the vast majority of society has found herself in an environment in which she is surrounded by girls considered less attractive than she. The girl then allows this unusual circumstance to affect how she behaves, generally resulting in a less compassionate attitude towards others, as she now considers herself a rare and highly sought after commodity due to her attractiveness relative to the other girls aforementioned.
Jill, usually considered a 4 out of 10, has been treating Jack, usually considered an 8 out of 10, like shit, because she's the most attractive girl at this party. Once she recovers from least ugly girl syndrome, she'll realize how inappropriate she has behaved.

When someone is rather unattractive before a weight loss, face altercation ( example, nose job, jaw realigning,etc...) was not full of themselves before the transformation, but after becoming so called "hot" or attractive and becomes a major bitch and having major changes in personality, etc.. super judgemental to other.
"Heidi totally got a case of "Ugly-Hot Girl Syndrome" when she got her face done. She is a total bitch now and completely full of herself."
