There are people like this in every race, and it is not true of all black people. I could say all whites' hair smells like dogs when I know this is not true. Don't feed into a negative stereotype, because I'm sure you know many black people who are the opposite of that. Our people are just being themselves. I went to Africa a couple of years ago, and it is cultural.
International blacks talk loud, and they wear bright colors.
Some of us have learned that to fit in in American society and certain social circles, we have to tone it down some. My wife says blacks at her work have confided to her that blacks envy blacks who are lighter-skinned than themselves. They told her the lighter you are, the more desirable you are, and the darker you are, the less desirable. If you're brown, stick around. This dates back to the slavery era.
