To be up in the family business of neighbors, friends, ex's, etc. offering advice with zero credentials to support it. Often the Nosy Neighbor Neller crosses the family line repeatedly and is therefore labled as Just Kidding Family. A Nosy Neighbor Neller usually has an agenda and is in high demand of attention even at the cost of interupting grieving family.
Someone please put a leash on Nosy Neighbor Neller and give our poor family some space. Geesh! Nerves
