As usual, I can't find the record, so I can't check it - but a Pigmeat Mama or references to pigmeat for sale are usually references to ladies of loose moral status. I'm pretty sure that the word is pigmeat, but I've been puzzling over the following word for over twenty years. On the other hand, it is quite apparent on a lot of old blues that the vocals were unclear because the artist would not be paid for recording if the engineer could clearly understand the improper meaning of the lyrics.
