A name for a girl who is very shady, and backstabbing. She'll say she's your best friend, but then try and ruin a relationship between you and your boyfriend. Kelsey usually will tell one boy she's dating him and keep two on the side for backup, in case her current boy isn't keeping her happy. Kelsey usually updates her profiles saying how "ugly" or "lonely" she is just so she can get the attention of others. Kelsey will also flirt with other boys when one of her boyfriends isn't around so she can feel like she's "loved". Usually has more friends than she can count, but still for some reason feels lonely, and also makes everything more dramatic then it seems.
So, I'm dating Kelsey now!

Yeah, you and three other guys...

I'm as confused as an uneatable cake.. Must be a "Kelsey".

If gravity didn't exist, Kelsey would still be on the ground.

Who ate all the PIES!!!??? ...Kelsey... Duh!
the bitchiest girl you'll ever meet . guys think shes an angel , but in reality shes a whore that cares about nothing besides her hair , how much tighter she can get her shirt and skirt , and how many penises she can get inside her vagina at one time .

girl: that's a kelsey , unless you want to pick up an std , stay away from her .

A big nosed bitchy blonde girl that closely resembles the character of Pinnochio. Extremely clingy and stalks her previous boyfriend who doesn't want her because she is rumored to have a penis. Kelsey is also another expression meaning... when you take a shit and the water splashes and hits the bottom off your ass thus covering your ass in toilet water. Also called taking a kelsey.
Dude i got my ass all wet from taking a kelsey.
Seriously, I always see her nose sticking out of the bushes when she follows me home. She is such a 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.

Kelsey is the dirtiest swear word in the English language. A Kelsey is a morally corrupt thief and has very few brain cells. This is because the remedial Kelsey snorts, smokes, shoots up, or pops them all away. The sluttiest of all females, a Kelsey has lost count of her bedpost notches. Kelseys are known to be dramatic, and they like to distort a situation and spread vicious rumors when you have been put on her shit list for trying to help her. Kelseys are known to be users and abusers and they can be the worst mothers in the world. One of these broads uses the crocodile tears to lure you in, then when you have served your purpose, she will warp your time spent with her and use it as sob story for her next victim.
Guy: Dude, why do you look so angry?

Dude: I felt bad for this girl I met because she "had been treated so badly". So, I took her in and fed her, only to have her steal from me and throw herself on the floor and yell "Why did you hit me?" when I confronted her in the most civil way possible. When I told her psychotic ass to leave, she started making up stories about how badly I treated her.

Guy: Dude, it sounds like you got Kelsey'd.
