When somebody is grilling on the barbeque and somebody else is standing over their shoulder the entire time telling them everything that they are doing wrong and critizing their every move.
Oh my god man, I was grilling up some steaks the other night and my wife was being such a Backseat Barbequer the entire time. It sucked!
