Victoria II German Nationalist - Excuse me, but I'm a Kaiserboo, not a Wehraboo

The Fuhrer and his virgins vs the Kaiser and his chads.

I genuinely searched throughout to find out who this guy was, but I got nothing. The earliest source is 21 January 2018 on r/battlefield_one (which I linked) saying "which one of you did this?", but he really took off after he was reposted on that very same day on r/just neckbeard things. I found him reposted on Imgur and other subreddits with people calling him a Wehraboo probably just to go along with the joke
