BTW, the behavior being described by the original poster is what is known as "gangsta" or "thug" culture, which is just the current lingo attached to a culture of poverty and dispossession that plays itself out everyday on streets around the world.

However, I do want to point out that the original poster also made what I consider to be racist suggestions that this phenomenon is strictly found among African American males. Nothing could be further from the truth, unless of course, that poster lives in an area where poverty is concentrated in the African American community, and there aren't other ethnic groups in that communitiy where they claim to teach besides European Americans who are presenting themselves as economically "better" than the African Americans. That isn't uncommon in some parts of the South, though it is becoming rarer nowadays that you would see such a black/white dichotomy.
