Oddbean new post about login | logout @Eòlach There are people that use that, there was a Pawoo or Baraag account called that, but since all of that happened after the meme, it was probably related to that. I don't know how common the term is.
It's probably common enough to people who actively use the dark web or are tech illiterate but less so with normies. I hadn't even known about it myself until Mental Outlaw mentioned it in one of their videos and all of a sudden I started seeing it everywhere.
