Need help with my book title!?

Hey guys, as the title suggests i need a help finding a title for my newest story. So its basically about a girl who is ur funny,sarcastic and mean girl..everyone is scared of her because of the tricks she has up her sleeves, but then a new guy enters the school, he seems to beat her at her own game, by playing much greater pranks with her..but as the story progresses her falls for her but she's ur cynical and non-trusting men kind of a girl. Anyway! I want a really hilarious type of title!! :)
