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: Damn, who's that dancing other there.
Guy 2: Idk but I bet its a Sierra.

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

Sierra is the type of girl who makes you smile she has brown eyes and dark brown hair that is braided she loves her boyfriend Johnny to death and will do anything for him she can be shy and not know what to say at times she isn't that good at math but is very smart generally in any other subject she can get pretty naughty at times and can be a turn on or tease but stays true to her lover she will never lie and always tell you if something's wrong she loves playing video games and have fun so if you have you have a Sierra you should defiantly hold on to her
Keep Sierra close to you because she's worth it

Sierra is usually a short blonde girl who is spastic and fun to be around. She thinks she is ugly, but she is usually the prettiest girl around. She is very active; she loves basketball, softball, bowling, ect. She has a low self-esteem. She gets mad easily but is the first to forgive. She is an all around great person.
Look at that girl!

Oh, she's a Sierra! (:
