Any girl who is obsessed completely with the Jonas Brothers, and pretty much every word uttered out of their mouth refers in some way, shape, or form the existance of the Jonas Brothers.
Girl: Like my shirt? I got it at the JONAS BROTHERS CONCERT!
Girl: I can't wait to get home so that I can listen to the JONAS BROTHERS!
Girl: I am going to marry Nick Jonas...we're simply perfect for each other.
Girl: OMG I HAVE THE JONAS BROTHER'S PHONE NUMBER!!! I AM GOING TO CALL THEM LATER TONIGHT SO I CAN GET THEIR VOICEMAIL AND HEAR THEIR BEAUTIFUL VOICES!
(and to all of these the guy would simply say)
Guy: Wow, get out of here, you Jo Bro Hoe!
