"Morphodite" is a word I knew and used myself as a kid, growing up in St. Louis, MO, in the 1950's, but (1) I knew it referred to a hermaphrodite (though I didn't learn the proper word until later), and (2) my friends and I were white, not black. It doesn't surprise me, though, that a word like that would change its meaning over time. After all, there were no dictionaries you could use to verify the meaning.
