Ugly Bird Syndrome is the name given to the phenomenon of unattractive females making an extra effort to have a pleasant personality because they have little chance of securing a mate using their looks.

The phrase has also been used by motoring broadcaster and journalist Jeremy Clarkson, in his description of a car which is unappealing visually, but pleasurable to drive.
- Mate, why do you keep hanging out with such a minger?
- She's got ugly bird syndrome; last week she baked me a cake!
