No it's when meat goes bad, you would sit there all day in the sun like leaving a pork chop in your car over night."pork chop go off"... is this another way of saying "we're having a barbecue" ... or ... "we're cooking out on the grill"...?
That can be quite fun, it all depends on the company of course.
I should have put like watching paint dry.
It is also the start of BBQ season, spring is here so warm days.
