I think this limp is fine at most party 2/4 tables so if your table is "average" it should be ok.

With the BB raising pf it is possible this is just a continuation bet and when you are behind with an over card and the bd nut flush draw you still can't fold this here. Raising is much better than calling because you have a chance to clear the field and get it hu.

Once he checks the turn I think you are ahead here a lot of the time and betting here gives you the chance to fold TT-QQ.
