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.

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.
