I enjoy watching the Kee & Peele. As you can hear around 2:00～, from this sketch, Troy and Mark are beginning to "exchange their words". Now they are saying, for example, Troy says to Mark "What the fuck do you think you are doing, nigger?", in response to it, Mark says "I'm doing my thing, nigger."
Now the question is, when African American people use these N words, which were once thought to be quite offensive, I think, does this imply voicelessly they belong to same groups? ( Although they are almost about to fight now ).
I appreciate answers and let me thank you in advance.
