5/10 blind battle: I flop trips, he overbets river..

[Superfluous Man]

Villain in the hand is QuasarX. Super loose-passive 47/14 pf, fairly passive postflop. Seems to c/minraise draws, occasionally air. He had earlier taken a similar line against me, but folded when I shoved the river (he also did not overbet the pot that time I don't think). Snap him off here or fold like a little bitch?

Edit: I really put him on an overpair on the flop/turn, but I think he's a lot more likely to c/c an overpair on the river rather than essentially turning AA-JJ into a bluff...yes i know "putting him on" something sounds stupid but i just mean that they comprise a large part of his range.
