Coffin Hugger
Somebody who cannot bear to part with their loved one at a funeral. They literally cling to the loved-one's coffin/casket until its prised from their hands....
"What's the silly bitch doing?"
"She's mounting the coffin, he dont need that no more, honey, he's dead! Get over it you coffin hugger!"
