A cold, heartless bitch that believes she is the most amazing person alive. She walks all over people to get what she wants and will throw a fit if she doesn't get her way. Sierras are typically dirty blonde with frizzy curls and a high pitched voice.
That girl is such a Sierra, did you hear how she was talking to Devon earlier?

a terrible person and you should never trust them. she will stab you in the heart with her pointy tiny tits. self-centered, horrible singer, acts like a little 2 year old, and never thinks about anyone but herself. she acts like the queen of everything and like shes the perfect girl when shes actually the complete opposite.
omg she is so mean! she must be a sierra.

This girl is probably one of the sluttiest girls you will ever meet. She is also known as four fingers and the stretch marks around her mouth can be seen from a mile away. If you ever come across a sierra, run in the opposite direction because her big gaping vagina will try to suck you up. Sierra is a whore and for all who know one, i feel sorry for you. Sierras are normally nasty ass blondes who don't know when to stop. They normally have nasty ass blue eyes and tiny boobs. They think they are the shit but just like every other nasty ass ratchet hoe you know, they are nasty as fuck. They most likely have a blue waffle, aids, herpes, gonorrhea, scabies, public lice, syphilis, chlamydial, crabs or any other type of std that you can think of.
Guy 1: "Sierra is such a whore."
Guy 2: "I heard she has crabs."
Guy 1: "Figures, she sleeps with everyone. I would'nt doubt it if she got pregnant."
Guy 2: "But she's only 14."
Guy 1: "Exactly."

Fat ugly chick who thinks she is popular when in all reality is the gossip of everyone. Rich and snood attitude. when she has a guy she is super clingy wont leave them alone. Horrible in bed. compared to that of a whale or pig and occasionally a cow.
She thinks shes so cool. She must be a sierra

A awesome girl who is kind of snobby but mostly sweet.
My best friend is a sierra

A girl who doesn't know her head from her ass. Someone who thinks she's better than she actually is. Quite bitchy and slutty to be honest. OH! And stupid. Very stupid.
Did you hang out with Sierra? No but I fucked her.
