A girl who has Good Vibes. She thinks she's super ugly but actually really pretty. She can sometimes have really bad depression but hide it really well. They have a past that no one really knows. They have really good taste in fashion, but have a different style then most. Most people like her. If guys like her they'll keep it a secret and reject that they do. She also doesn't think she can sing but people tell her other wise. She stands up for what she believes in and defends people. They have a smile that lights up the room and really pretty eyes. She doesn't date a lot. If she likes you its obvious. She can get made fun of sometimes. If she has a problem she isn't going to tell anyone. At party's she's the life of it. She loves to dance.

Guy 1: You're probably right. I mean look at her.
