Mileyitis
When someone listens obsessively to the new 'rock' diva Miley Cyrus, they catch Mileyitis. Mileyitis is a love of crappy music and leads you into a blackhole of standing up for little miss Cyrus and her music. It often ends in death (of your social life) and/or bad fashion sense.

Girl 2: Woah, severe case of Mileyitis!
