butter and egg man
Why don’t you take me pretty mama, make something out of poor me?
I’m just a butter and egg man, just as soft as I can be.
—Papa Charlie Jackson, “Butter And Egg Man Blues,” 1926
A disparaging Jazz Age term for a small-time businessman playing the role of a free-spending playboy, particularly on jaunts to cabarets. This meaning is not evident in the above song; nor is it evident that the singer actually understood the phrase, one of the few fashionable slang terms to trickle down into blues recording.
