A Girl who grew up all her life unattractive until High School or College when she then "Blossomed" into a really hot girl. Unlike naturally pretty girls though, her self-esteem is pretty low (As it'll almost permanently be for life) but, she has a good heart, personality, and soul because that's all she could afford to have when she was unattractive. Also, any girl with UDS, will go out with any guy cause to her "Looks Doesn't Matter. As long as they have a good Sense of Humor." As long as they never realize that they're a Ten, they'll always be humbled and down to earth.

A person who did not develop fully (therefore making them ugly) up until highschool or later and becomes pretty and they are really nice and have low self-esteem.

A crass response to being pleasantly surprised by an outcome you did not foresee happening.

Addition to the entries above:

A sudden awakening from UDS can have extreme big head reactions. This unfortunate turn of events is one of the primary foundations of the camwhore , a girl who has been sheltered/shunned from sex - but suddenly realizes she "has it".

A person who is as ugly as Donald trump

When a person with a good personality is actually attractive.

When a person -particularly of the female persuasion- feels the need to post excessive pictures of them self with their lips pushed out in "duck face" and more-often-than-not with copious amounts of cleavage, on the internet.
