Sierra

Sierra’s are cool, and sometimes chill. They can be wild, and crazy. At dances or parties they are the most fun and the wildest dancers. They aren’t afraid to show who they are. They can be psycho sometimes, but at school and work they can be chill. If they are with their friends though be prepared to amazed by a psychopath. Lol They are most the time always naturally beautiful! You are lucky to have a Sierra in your life If you do! They are also real good friends and are always there for you, but prepared they are pretty sassy.
Random guy or girl at party: Who is that hot girl over there?

Other guy: I don’t know she is hot though. She is probably a Sierra
