Puberty. Because Justin Bieber has singlehandedly redefined it.
Bieber Fever has caused several of Justin Bieber's concerts to be cancelled, because he can't hit the high notes anymore.

The non medical term given to the world wide obsession with the 16 year old "wonder" that is Justin Bieber. "BieberFever" seems to have peeked to an all time high since she had her own movie made about her extremely *cough* amazing and self deserved *cough* success.
Ahh she's just got BieberFever dude- they say the cure is to listen to some heavy rock
