Katie 

A Katie is a girl who gets around like a bag of chips. She is usually in several "relationships" at one time, and can't get a clear gripp on reality. Not as attractive as she thinks she is, and has a hard time NOT sleeping with just about anyone. Katie's are known to be stubern, rude, lazzy, slutty, fake, and in most cases free loading children.

Are you ever going to grow up, or do you like being a Katie.
