A mental illness that usually begins around age 10-13 and will usually go away by age 21. It is the only mental illness that is contagious and seems to occur frequently in people who have severe hearing loss, are gay or are pedophiles. There has been some success in curing disease by exposing infected individuals to music and other art forms that are of some actual value, quality, and talent. Another effective but very controversial treatment is truth therapy where the infected individual is let in on the secret that Bieber is actually a female cat that was involved in a severe accident during secret testing at area 51.
It is so sad watching this Belieber disease destroy the youth... it's worse than polio, aids or even Leo Sayer.
