I’m not sure why people are still talking about it as some insular 4chan slang. Like much of 4chan culture, it’s spread to most of the rest of the internet by now. Hell I’ve seen “based” comments on HN.

I shun most of the internet these days. HN and (German) reddit are the only "socials" I use. I have no clue what is happening on the wider Anglo speaking internet, especially Twitter and such is completely alien to me.
