This is some classic ghetto slang that arose from one of John Witherspoons classic routines that can be seen in "
Hollywood Shuffle".
Hoecake is a cake made from some type of indian recipe, it's called
hoecake because in the old days people really cooked them on the blades of hoes.
The whole slang punchline for this was John saying he wants to start marketing
hoecakes for his restaurant because, "Hoes gotta eat too!"
