An oblivious, ignorant, foolish girl. One who does not consider others.
Girl #1: "I only care about a few people in the world!!!" evil cackle.

Girl #2: OMG, she just pulled a 'Kelsey.'

When someone initiates a conversation with the opposite gender and claims to others that the person they talked to actually started it and wouldn't shut up in order to avoid sounding desperate. usually occurs when a younger girl talks to an older guy
wow, she totally pulled a kelsey on you

A horrible, ugly, poser person usually fat. Weird eyes and big teeth. Ugly laugh.
person: Ugh, kelsey thinks she's such a NERD.
you: I know, I wish she'd commit to her claims of being suicidal and do it already.

A sloppy whore. Generally tries to fuck every guy in the room at once. She's a stupid little bitch that likes "meat". If you have alcohol, you can get this slut. She loves to party and get shitfaced. Shes been fucked so many times she is the most loose girl EVER!
Guy 1 "Dude, Kelsey's vagina is so imminence that you can fit the whole U.S. Navy inside her!"

Guy 2 "Yea, all those semen!"

Psycho Bitch that has no real friends. She cant be trusted and made her only friends miserable with her snide comments and judgements and eventually drives them away. She isnt confident about herself, which is why she constantly brags about what little she has and insults her friends. She couldnt get a guy unless he was a man whore. Shes an awful person who is rudely inconsiderate and competitive. She never wins at anything, so basically a Kelsey is a failure at life. If you meet a Kelsey just walk away and save yourself the trouble and the drama...
Oh thats just like her, shes such a Kelsey!
