In the brewstew lore, he's known as Michael's stepdad. He's an abusive father, calling Michael FS (fake son) while calling his daughter RD
Michael's stepdad: Ah what the hell?! RD why do you keep saying that?! Fake son, get your ass over here.
Michael's stepdad: Did you teach Tabitha this dolphin dick?
Michael: Uhm no. I don't even know what that is
Michael's stepdad: where the hell did she hear it from?!
Michael: I don't know, we go to Kmart a lot, maybe she heard it here
Michael's stepdad: God damn it, FS! You're getting 10 across the ass!
