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.
