Diagnoses: Bieber fever
Symptoms: obsessive thoughts of Justin Bieber, stroke, heart attack, and seizure possibilities if meeting him, crying hysterically, screaming at a shrieking tone, fainting, and falling in love. Falling in love is most likely permanent and irreversible.

If you have heart conditions or medical issues, you should consult with your doctor before watching him on TV, looking at a picture of him, or meeting him in person. It is most common in young girls.

So far this fever is incurable.

The term Bieber fever applies mainly to prepubescent girls with a few exceptions. Most people that actually have bieber fever are either:
1. Deaf
2. Possesing an IQ below room temperature
3. Pedophiles
4. Knowing nothing about music
5. Under the age of 10

Few people know the cause of Bieber Fever, but it generally causes any girl years younger than him to love him and anyone with a tiny bit of manliness or sense of music having a strong hatred towards the girl they call Justin. Usually this would cause someone to go to jail and eventually get shanked multiple times, but Bieber is a celebrity and is known to attract miles of fools that can actually listen to his sqeaky xbox live-esque voice. After concerts, the crowds are generally worse than riots, and the Local Swat teams have to hold back the now savage fans.
Dumbass Girl: Woo! I have Bieber Fever!

Person with complexity above a fruit fly: He makes horrible music, how can you like him?

Dumbass Girl: STFU! He's very talented

Person: *Sigh* (Procedes to daydream about Bieber getting cudgelled)

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
Constant searching for gossip about Justin Bieber
And the developing of Edward Cullen Disease.

The only cure is more cowbell.
I've got BIEBER FEVER, and the only prescription is MORE COWBELL!
