yo mama 's so old she has a separate entrance for black dick .
Do you really mean this about someone else's mother?
If black dick is what I was talking about, then yes I did mean it that way.
It's one thing to insult your friends and/or rivals in a joking manner like this, but it's wrong to insult someone's mother at the same time.  This isn't someone who has done anything to you, and jokes about segregation are in bad taste, anyway.
