Kick Potluck Dish???

I've been invited to what I know will be a kick New Years Party. We will not be staying all night (my babies won't last and there's tons of crazies on the road)...BUT I still want to bring a great dish! I was thinking buffalo chicken dip, but my mom is bringing her most excellently hot buffalo wings so I need to think of something else. Any ideas? There will be about 30 of us there...my other thought was sweet/sour meat (bag premade meat 1 bottle chili sauce, 1 bottle currant jelly)....other thoughts?
