Where did "One Guy'd" phrase come from?

This may or may not be Hololive specific as it generally applies to any streamer lol but I first heard this term from either a Magni or Bettel stream (can't quite remember). And now it seems like a lot of the HoloEN members use this phrase quite often. Was it something Hololive started? Like how Ame coined "Idol Meeting"?

Otherwise I just assume it is streamer lingo that really caught on more recently. Just a random thought.
