Villain is very loose and spewy.

Did this guy actually hit the flush on the river or what?

wtf are you doing get it in on the turn, you have the second best kicker and he likes his hand
there's no way I'm folding the river either

At these stakes, people may move in for $.78 with anything! But I agree with iopq, you should have reraised all in on the turn.
