It’s well known that orcas pick up “games” that are basically fads. They find stuff to entertain themselves and keep at it until they grow bored of it.
When I say strong, I mean that a trend is it dominates and defines as decade. All those things you mentioned are trends that you associate with different times, but there are far fewer things you can dress up as and people will think: ohhhh are you "from the 2000s".
They exist, just I'd argue it's not as strong as the 90s
