flopped full house

[Vehn]

Good loose 30 game. Laggy type opens utg, good but loose player utg+2 calls, I call with 22, bad loose player calls, one more cold call and both blinds call. Flop 333, checked to utg+2 who bets. I raise? MP calls, folded to utg+2 who calls. Turn 4 utg+2 checks I..? Do I have the best hand here enough? Is this flop a fold? I thought this was interesting.
