In the tower industry the term "Pork Chop" refers to a safety climb cable grab device that resembles the shape of a pork chop. (Funny how so much tower terminology uses food terms. When you are working on a tower for 12hrs a day you can't really be expected to climb down for lunch.
Hey, don't start climbing that tower without your pork chop.
In the old southern USA, it meant something to do with a vagina. The reason I guess this is that Memphis Minnie sang a song called 'I'm selling my pork chops (but I'm giving my gravy away)'. She often sang songs about prostitution (Can I do it for you?, Down in the Alley, Kissing in the dark). No Idea what she meant by 'gravy', but for sure it will be related.
