Katelyn is an all around amazing girl. If she likes you she will usually insult you or call you rude. She has an amazing sense of fashion and takes school very seriously. Katelyn’s are most likely to date someone with a name that starts with a K such as Konnor.
Boy: wow! Look at Katelyn.

Boy2: Your name doesn’t start with a K, you are screwed.

Get the Katelyn mug.
A girl mostly always blonde probably friends with a brunette, this is a girl who's lost in the world and cannot find herself. She can be a bitch and air head sometimes but in the end after being a backstabbing bitch her brunette friend she stood on will still be there for her
Person: hey did you see what that bitch just did
Brunette friend: hey she might be a bitch but she's my best friend, she's a Katelyn

Katelyn is usually a very unsightly girl, with a variety of a chunky figure. Katelyn can often than not be confused with an atrocious fat mammal, like a cow, pig, or a moose, which makes her utterly atrocious. (pun intended). A Katelyn always has a corpulent figure, along with a corpulent face and an obnoxious attitude. Katelyn will have a distasteful group of friends which will also have a nauseating body and face.

Stay away from these godawful barbaric things they call a Katelyn.
Person 1: omg look at that thing!!! It is so frugal it will probably kill the people around it with its fat juices.

Person 2: omg yh that’s Katelyn, you know the very oversized girl that no one likes.

Person 1: yh we better stay away, she is very scary and gross.

Person 2: agreed

Someone who may look like a sweet person, but truly, she is a bitch. Her name means, evil, and she is always there to put you down. Even if she calls you her best friend, she will always try to find a way to make your life miserable.
Person 1: Holy shit that girl is a downer
Person 2: Well duh, that's Katelyn
