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.
