Not quite- in Appalachia, most homes have a porch. Appalachia is, generally speaking, quite a muggy place, so most people sleep inside and then spend their time outside on the porch. The porch plays the same role as a living room or den in other parts of the US.
A porch thief is basically the same as any other burglar, but they will (almost) exclusively steal from porches because it is often less risky than stealing from the rest of the house.
Because of the important role of a porch as a primary living area, porch thieves can make off with family heirlooms, money, games, furniture, children’s toys, and even TV sets.
I notice people of certain age groups were fine with names like that, even though they seem like rather unfortunate names, especially as a given name rather than a nickname.
A coworker of mine has a grandson, “Butch”. Kids always getting into trouble, though.
