It's called Justin Bieber Syndrome...
...for every 5-100 people on the Internet, 1 will mention Justin Bieber. About 1 in 5 preteens and about 1 in 100 adults are affected. Kind of like Godwin's law I suppose.
Signs of this disorder amongst many include mentioning Justin Bieber, insulting Justin Bieber, comparing other musicians to Justin Bieber, and setting your Myspace background to that of a photo of Justin Bieber. All I can say, be lucky you have ASD instead of JBS.
