a moniker for legendary DC pimp John D. Thomas.
"Working that game like my name's Blackmaster.. I finese that ass..I'm stirring that jo'nt up like a hot pot of grits... I hits.. my groove faster.."
Slang term from the 1920's meaning a lady's man. But is now used for men who enjoy the butt sex.
So, really it can go both ways, but it definately means a man-whore.
"He's a slutty, cake eater."
