Someone who acts like they are your friend but is really a manipulative backstabber. A bad friend would be someone who is jealous of you and tries to compete with you and take over your life and replace you in all aspects because their life is too sucky and they can't come to terms with the fact that they were just lucky to be your friend in the first place.
I made a horrible mistake when I became best friends with Jessica because she ended up being a bad friend. She tried to compete with me, talked about me behind my back and tried to steal my friends and boyfriend.
