You're addressing the wrong person, for one.
You're going to smack someone across "the chops" for using slang here?
cack-broad n. =cackle-broad. 1942: "I knocks de pad with them cack-broads up on Sugar Hill." Z. Hurston, 89. Cf. kack.1
So it's not slang. It's a typo in the title. Ergo, open-season.
