The "If you hurt him/her I will break you" talk given as a warning to a romantic partner from a concerned party, usually family or a close friend.
Father of the bride: "I have a shovel and 30 acres of land. If you hurt a hair on her head, no one will ever find your body."

Groom: "You don't need to give me a Shovel Talk, sir. I would rather die than hurt her."
