UDS

pronounced -you-dee-es-

Ugly duckling syndrome

A person who has grown up as an physically unattractive person but later becomes good looking. As a young person they were able to develope a non-bitch attitude and were able to have some developement in their brain. Thus they get a very likeable personality because they can't rely on their looks.

When they became attractive they have a great personality unlike people who grew up knowing that they are better looking than other people.

Hence Ugly duckling Syndrome

ud

a web site found on the internet were almost anyone with internet and literacy (not much required) can define whatever the hell they damn well feel like defining. The ultimate use for the 1st amendment
Why the hell are you looking up the definition of ud, you are already here. Then again, why am I even defining ud if there is no real reason to search it on ud?
