The disease that consumes the brains of young females, and makes them literally go insane. To be around a large group of these infected girls one mention of the name "Justin Bieber" will cause chaos and you would probably be trampled to death. These delusional tweens also believe that they will marry Justin Bieber, news flash that is not going to happen. There is no known cure to "Bieber Fever" most likely it will be the next actress/singer to be queefed out of the murder machine that is disney.
