I think I raise this board and fold to push...
Even a passive villain could be doing this with 77+,44-33,AQs+ and against those you have a fair bit of equity

if he's so passive that you think he's only doing this with 77,TT+,44-33,AQs+, then it's close to a coin toss and I'd lean towards folding ;\

I think flat calling here is wrong because you're giving BB great odds to call for whatever garbage draws he may or may not have, so raise or fold :S
