Top definition
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!"
