Sierra is the type of person who lights up a room with just a smile. She has a really nice butt. She is tall and is usually a dirty blonde. She loves hugs. Sierra is a shy person, she loves when people hug her even if she does not show it. She is really faithful and will never use a guy. She has a bunch of friends. If someone hates her it is because of jealousy. She is the best person you will ever meet. If she gives you a second chance you better take and hold it tight. It means she really loves you. Dont mess with her because she will go physco.

Sierra is an awesome girl who is always there for her friends. She is freaking gorgeous, and all the guys secretly want her. She doesn't care for relationships, but if she does open up to you, you better never let her go because you'll never find another like her. Her ex's usually regret letting her go, and constantly try to become friends with her again. She's extremely athletic and is good at pretty much all the sports and has an amazing body. Her legs or her butt are usually her best feature. She loves going out with her girls and having a good time. Sierra's can be shy at first, but get to know her and you're guaranteed to have a great time when you're with her. Sierra's are extremely smart, with their strong subject being either history or math. Sierra's stand up for what they believe in, and aren't afraid to fight for their beliefs. Sierra's are amazing girls, that everyone wants to be friends with. As they should.
I know, Sierra is my best friend! Everyone is friends with her..
