A female who is significantly less attractive at close proximity than she initially appears from a distance.

- Nah, man, that's a decepticunt if I ever saw one. It might be just a shadow, but I'm pretty sure her whole face is concave.

- Bummer.

A female who can pass as a decent human being . Most people like her . But behind closed doors she is human garbage. A black hearted pure evil demon. Who could trick the devil himself. Impossible to see it coming she projects a Trance with her sweet mermaid like songs that come directly out of her battered and war torn vagina and lures you to you icy cold death ... often perceives as kind sweet and caring and beatiful ..but dnt be fooled she is as fake as plastic tits
