** NOTE: The 's' on neckbones is purely optional.
I live in SC, and even I've only heard this one a few times. But it's a keeper. Some folks apparently cook pork neck bones. Wash 'em up, throw 'em in a pot. After that it's anyone's guess. Used thusly: "You ready to bolt? Then it's on like a pot of neck bone!" See also Redneck.
