The dark eighties refers to the period of time in popular culture, between 1983 and 1990, when there was very little original thought occured. There was a mass market culture ruled by the common denominator.
For some reason bands like Wham! were actually popular during the dark eighties.
Way back in the dark eighties, there was a band, M.O.D., which stood for Method of Destruction. They were the orig right wing hate band. On one of their albums, which may have been called Speak English or Die, they had a song called, A.I.D.S., which stood for Anally Inflicted Death Sentence.
The lyrics of M.O.D.'s A.I.D.S. go something like, "that's what you get for having a penis up your ass. Anally inflicted death sentence."
