A girl who has a long list of people who despise her. A girl who stirs shit and is a complete bitch to everyone she knows. She will stab you in the back and will never pull her head out of her own arse. A Hayley normally has blonde hair and looks like she's been smacked in the face with a brick. Dont trust a hayley.
"I hate that girl, bitch!"
"She's such a Hayley"

Jun 24 Word of the Day
An exclamation made when your friends or family are teasing you to a point where you can't handle it anymore and a hissy fit is in order.

Derived from a YouTube user's famed outburst following Britney's lackluster performance at the 2007 VMA's.
Sarah: 'OMG Susan, I can't believe you are wearing the same skirt as yesterday. Oh, and by the way, EVERYONE knows what you did with Kevin on the weekend. Plus you look a little fat, are you retaining water?'
