If I hit trips on the turn I probably wouldn't bet ~3/4 of the pot when a 1/2 pot bet achieves the same means and is more likely to induce a bad call. I think this bet is trying to buy the pot because a boat doesn't worry about the flush or straight and trips can still lay bad odds to call the river along with having plenty of outs.
Against a thinking player my fav. set line is: check call flop and then pot the turn. This works especially well if the flop is rags, but the turn is an overcard (assuming the overcard hits the other guy as well) - I got ihategnomes goot with this in one of the gauntlets :P
