That's right. You are the tumblr scholar yourself I see!  The back story on him for the others, and I got this from someone who knows him irl: He chats up underage fatties online to get with them. He's over 30 by now, but I think he tries to portray himself as younger. He's a chubby chaser but secretly (or not so secretly) makes fun of them behind their backs. His brother's gay so he's been doing a whole fake "gay pride" thing too, but apparently he's quite conservative in his views.  He pissed off the tumblrinas because in his fat acceptance blogs he was writing how he is anti-abortion but at the same time a progressive feminist. All in all, he's just some creepy loser.
