Kelsey 

A name for a girl who lurks facebook. Not only will she spend hours liking every one of your posts, she will know things about you that you don't even know about yourself.

Damn, that girl is a kelsey. She's been lurking facebook all day!

kelsey 

most bad ass, extremely athletic and sexy person, typically a smart ass but cares a lot about the people he is closest to, hard core and slightly cocky but never lets it all go to his head. typically the quickest with comebacks, loves to listen to people, and enjoys proving people wrong. always up for a challenge and hates losing!

-that guy is so sarcastic, its funny
- i know he is such a kelsey

Kelsey 

A girl who generally is a bitch. She actually doesn't know it so it is quite sad watching her wander around acting like a complete bitch. She often condones and engages in slutty behavior, as her future job will most likely be a whore.

Oh gosh I cant believe you even looked at Kelsey} she is so ugly and [nasty that she probably is a few molecules away from poop.
