Retrovirus

A virus that has been until recently out of fashion but was brought back by a trendsetter thus making it cool to have again.

Charles Bronson: "Oh man, did you hear Johnny Hurn is bringing back a Retrovirus?"
Stan Lee: "So which one do I need to get? Gonorrhea? Syphilis?"
Charles Bronson: "He's bringing back them all!"
