I'm torn. Calling is probably neutral EV. He could be pushing with a worse hand, but he could also have AK. KK/QQ/JJ wouldn't surprise me - a lot of these dumb short stacks see the card they hate the most and push just because they're mad about it, or something. It's a weird reflex they have.

I also dislike the flop raise. What are you doing there? If you're bluffing or even setting up a bluff for a later street, don't price him in... at least give yourself a chance to win. On this raggedy board it's likely he missed, but he's not folding overcards for a min-raise and he's definitely not laying down an overpair.
