A condition in which the voice of a young boy does not mature from a high pitched squeal, akin to the voice of Justin Bieber. This may be followed by a sudden obsession in Bieber's music and subsequent fandom. Extreme cases may also result in a miniature penis and/or mangina.

The biggest epidemic since the Black Plague.
Millions of women aged 3-60 have been affected by it. Although most men are immune, a couple have shown small signs of this deadly illness.
Symptoms include:
Loss of friends
Tone-deafness
Constant searching for gossip about Justin Bieber
And the developing of Edward Cullen Disease.
The only cure is more cowbell.
