Why would a girl say this?

The ***** is jealous of you. That is the only explanation I have. She is jealous of you and the fact that guys like you irritates the hell out of her. So she tries to make you look like a on the internet. I know some chick who was the same way with me. Actually, she had a bit of a crush on me, but didn't know how to come about it. Keep doing what you do cuz jealousy is one hell of a compliment.
