A girl who stalks her ex boyfriend. A girl who's very rude, and annoying. A girl who runs her mouth, but never backs it up. A girl that prefers inanimate objects for pleasure rather than a guy. A fake person. Someone who loves attention.

Kelly has been mooching rides off me for several years. She never offers to pay for gas and one time my hand was broken and she still made me drive her. I do not like this girl or her ethics/morals.
Kelly please get out of my car.

A girl that can not go very long without seeing the guy she likes. She will make multiple trips to see him in one day. She will do anything for him even if it means jumping off a bridge. She lies alot and can get away with anything. People belive her very easily. She has a sister that likes to tackle people and go through your phone. She is very funny but can act like a blonde. She does alot of stupid things. She is obsessed with justin bieber.

Someone who does stuff for attention, sometimes in a good way but mostly it's just annoying for everyone around them.
"Omg that girl is being such a Kelly, she only post that picture to get likes."
"Go change, that shirt makes you look like a Kelly"
