What are you talking about? I've never even heard of a black gangster. Gang member, yeah, but not a gansgter. Gangster's, the real ones, are hardcore Italian.
wannabe: "Yo, sup, man, why you gettin all in my crib and face, dawg?!"
gangster: "I prefer that you speak english if you do not want me and my boys to see that you are "six feet under" very soon."
wannabe: "Whatchyo talking about, foo! That be some tight sheet!"
gangster: "very well. you have made your choice. I shall see that you get a proper funeral with the fish, so that you do not disturb me any longer."
