Ear AIDS
A highly contagious desease, spreadible though sound; mostly music. For each individual, catching this desease varies by song or sound. Since most parents are not up-to-date on modern music, they might get Ear AIDS from many hit arists, like Ke$ha, B.o.B, 3OH!3, etc. Kids, on the other hand, are so up-to-date. They might catch Ear AIDS from old artists, like Bruce Springstein, Johnny Cash, Madonna, etc.

WARNING: The number one source for Ear AIDS (Adult, or Child) is Justin Beiber.
