Bieber fever

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.

Potter Fever

Similar symptoms to the epidemic widely known as "Bieber fever" but with a level of maturity and elegance not seen amongst those suffering from "Bieber fever." Strikes most often prior to the release of a new book or movie about or relating to Harry Potter. May leave victims in a euphoric state that will, when it fades, plunge the victim into Post Potter Depression.
Bill: "When the final Harry Potter movie came out, I felt like I had Potter Fever."

Bob: "Careful Bill, Potter Fever and Post Potter Depression often go hand-in-hand."
