Drawy board out of position, turn is gross - what to do?

[BrassMonkey]

UTG plays tons of hands and acts kind of like a maniac. Button is a retard who plays pretty much every hand, usually limping in. BB plays a lot of BB for a raise. My AJo almost certainly has a pot equity edge here.

Flop sucks, but I pretty much have to bet. Hate so many callers. Turn card is awful, so what do I do? Bet/fold? Check and see what happens, giving myself the option to fold?
