Leave Britney Alone
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'a.
Girl 1: 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?
Girl 2: LEAVE BRITNEY ALONE!
