Kayleigh is someone who is pretty, and hilarious. Kayleigh is a person that will be a bitch if she needs or wants to be, they may act nice but if you say something they don't like they might have a whole change of attitude towards you, sometimes you don't have to do anything to get on their bad side, it could have just been a misunderstanding.
Guy 1: Is that Kayleigh?
Guy 2: I heard she ended a friendship because the person was called a bully by 1 person.
Guy 1: Wow I would not want to be them.
