I'm surprised at the number of people on this board in particular that don't know about Jerma.
He was a big TF2 personality back when it was relevant.
He has done a ton of crazy and high effort streams like the live action Jerma rumble, chat controls a robot twitch carnival, digging up shit in the Nevada desert, and whole bunch more memeworthy stuff.
He's the imposter is sus guy
His rat movie is used in a lot of rrat memes.
He has interacted with Nyanners on several occasions.
Hell Gura just recently did her equivalent of a Jerma joke which some of the comments even reference
