Jamie

Most often has dyed hair
A girl who you believe is a kind caring person, she's pretty and she knows it and will use it against you given the opportunity. When your friends with her she is an amazing person and a great friend and is always on your side, but as soon as you manage to get on her bad side she will set out to ruin anything you have. She will run your name into the ground and broadcast anything you told her to everyone around her. She will play games with your insecurities and try to get you to fight her, but then acts as if she's better than you and like she's in the right when she truly isn't.

If you can you should never trust someone like her and never tell her anything because she rides on a short fuse and even a look can send her off the rails.

Person 1 " Hey, i thought you and her were friends... she's talking shit about you.
Person 2 " Oh you must be talking about Jamie..
