Katelyn's are usually girls with an amazing personality but choose to be with the biggest jerks ever. She deserves way better than what she gets. She is an amazing girl, but is a really big mooch. She asks everybody for everything; money, food, rides to places. You can either love or hate Katelyns.
John: Hey did you see Katelyn today?
Paul: Yeah she was with her boyfriend though, that guy is a total douche.
