Get the the eighties mug.
The decade of all things of slightly bad taste, including (but not limited to): spandex, shoulderpads, crack cocaine, the beginnings of hip-hop (Grandmaster Flash), the Falklands war, early synthesizers (and, then, also Human League, Kraftwerk etc.). People back then seemed to love acting slightly queer, for example Frankie Goes To Hollywood with their pornstar moustaches.
