This is a list of the things in nerd culture that passed me by even though I identify as a weird nerd:
Dungeons & Dragons
Cthulhu and all of H.P. Lovecraft
Video games (until 2014 when I bought a PS4™)
FFFFOUND and MLKSHK
Bitcoin and other cryptocurrencies, the blockchain
Indieweb, "owning my data"
I sometimes feel like I missed out on those things, but other times I feel like they weren't for me anyway.
Ways of thinking that have passed me by, that I've read about, but haven't actually done with anybody:
Agile software development
