Yeah it’s super weird how these internet cultures developed their own idiosyncrasies that show up in real life. Nerd culture kawaii humor around the turn of the decade is super recognizable as well, waffles being a meme (not the blue ones), and lolcats (debatably appropriated from 4chan), Natalie Dee comics. As these things were commodified during the 2010s into pop culture it all sort of washed away subculture connection. There’s a kids book series now called Narwhal and Jelly where the dialogue is basically all internet-speak from this era and I’m guessing most parents have no idea and just think its a quirky kids book.
