> That's how "I use Arch btw" became a meme.

Not really.

The meme is from 4chan and the /g/ board that had some origins around 2011/2012. Gentoo was the main meme before this.

After 2012'ish the meme-culture from 4chan became mainstream internet culture with the popularity of reddit. Nothing has really progressed beyond that.
