Someone with large boobs that are usually the shape of coconuts. A Kaitlyn is also someone who likes it rough.

She is the best person in the whole world. Smart, funny, nice, cool, beautiful and athletic. If you hang out with her, She will be an amazing friend. All the boys are literally begging to go out with her. Even the teachers admire her! But watch out: don't get on her bad side.
Guy 1: I just had the best day of my life!
Guy 2: Why?
Guy 1: Oh, I was just hanging out with Kaitlyn.

A beautiful, tough, independent girl in a jacket. she'll help you through thick and thin, even at your worse. If you ever loose her, it won't taste bitter, but you'll remember forever.
I wish I knew more Kaitlyns.

A retard with self esteem as low as Australia’s exosphere who has a major Fall Out Boy obsession, snorts soy sauce ramen packets like cocaine, has crippling depression, sings like a dying cheese grater on helium and sulfur hexofluoride, and calls herself out on websites like this...
Kaitlyn: “Merry Christmas, (I could care less)
Sister: “when will you stop making FOB jokes?”
Kaitlyn: “until your breathing stops”

Kaitlyn is a girl, who usually has a lot of friends. She sometimes wishes that she wasn't as popular as she is. But, she still enjoys and loves her friends. There is a LOT of drama in her life, so if you can, comfort her as much as you can. She has awkward histories that she wishes that she, someday, could forget, but knows that probably, isn't gonna happen. She had a friend that moved away and misses how much fun they had together. She has a crush on a boy that she knows that she will love for the rest of her life. She also has quite a FEW pets, but since she is loving and caring, she remembers each and every one of their names. She may seem rather simple at first, but if you anger her, she will be ready to fight. That is all I'm gonna say about her for now, and... if you are wondering how I know so much about 'Kaitlyn', its because I am one of them.
Kaitlyn's friend: "Did you hear that Kaitlyn has a crush on ____?"
Random Person: "Really? can I tell him?"
Kaitlyn's friend: "He already knows bruh!"
Random person: "oh... are they together?"
Kaitlyn's friend: "stop asking questions..."
Random person: ( :| )
Kaitlyn's friend: *slowly backs away...
