Is there a hidden "mini-decade" between the 80s and 90s?

[Simfan34]

There was a cultural period, perhaps best encapsulated through MC Hammer's trousers, which fits with what you are talking about, from around 87-93. Likewise what we know perceive as the "60s" is essentially the period Angus describes, before that it was what one might call, for a lack of a better term, the "Mad Men era".

But the loud track suit comes to mind when thinking of that perioid.
