Get the Katelyn mug.
A girl who can be really cute but never brushes her hair or teeth. She has multiple boyfriends, with the names of Kayan, Aengus, Aiden, Seth, Elijah, Phillip and Conrad. She is obsessed with Roblox and loves to annoy her siblings.
Sister #1: "Did you hear about Katelyn getting another boyfriend?"
Sister #2: "Yeah, I heard she got one on Roblox this time"

A Katelyn is the most amazing girl you will ever meet. She is funny, cool, and is completely gorgeous. She has the best personality in the world and absolutely amazing. If you ever know a Katelyn you're lucky, if you ever get to date one, you're blessed by God. Don't ever lose a Katelyn.

I love Katelyn because she's the coolest and most amazing girl I know.

An all out amazing girl. typicly with brown hair and bright blue eyes. she can be shy, but around the people shes close to she can be absaloutly histarical. she has good friends that love her to death. she loves her family more than anything. she beutiful amazing and sexy. But she young at heart and somtimes she wants to do it all over again. when she dosent have a boyfriend she may seem happy but inside shes the lonleyist girl ever. shes hopelessly romantic and loves taking pictures. she may seem happy but shes good at hideing her true feelings, so don`t be fooled. but she still is one of the greatest people you could ever meet
she seems perfect
thats why her names katelyn

She's a little bit awkward and completely ugly, but kinda cute at the same time. She loves books, tumblr, and music. She likes to cuddle and she's super weird. She likes nerdy things. She has an average body, but its amazing if she knows how to work it. Some try to be like a Katelyn, but often fail because she's so different. Her obsessions get a little out of hand sometimes, and often fangirls over silly things. She's very indesicive.
Person 1: ew look at her she's reading and looks really awkward and is wearing a (insert fandom here) shirt again

Person 2: that's Katelyn! She's fabulous!
