A pandemic sickness that infects the weak and unprepared who are easily satisfied by seven-year-olds singing. The probability of infection depends on the carrier and the exposure victims. It feeds on people's minds and souls, and its path of destruction is powered by attention, whether it be good or bad.
Symptoms include sudden interest in a certain brownish-haired seven-year-old looking boy and other people often commenting on how stupid you are. You may also want to check for posters in your room featuring the aforementioned child. It is best if you do not contract this disease, or else you will not have the sanity to treat it, and no one else can help you. If you have a friend who is infected by this, we're sorry.
Methods of prevention of Bieber Fever can include listening to real music, instead of a small child attempting to sing. To prevent this disease from spreading too far, mentioning of the child known as Justin Bieber should be kept to a minimum so as to keep people from giving him attention.
Person A: Omgomg, I have Bieber Fever, omg, Justin is soooo hot!
Person B: Omg me too! What about you, C?
Person C: ......NO.
