It is how they distinguish you from other people. Its nothing to do with the fact that you are black and they feel that they should point it out.

Its just...if someone asks about you and who you are because they don't know if they have seen you or something. The easiest thing to do first off is say "yeah, he is that black dude..." obviously, if you are the only black dude and there are so many white dudes it is the easiest way they can identify you to someone who doesn't know if they have met you or something or seen you.

If there are more black dudes, it would be sumthin like "yeah he is that black dude that wears the blue hoodie..." or whatever clothing you wear.
