He's been working like a nigger all week. What? I'm saying that they work hard, how can that be racist?
What exactly are you trying to say when calling people "niggers" in this context?
Er... to be more precise, nigger refers to how hard the blacks work.
The word nigger has a negative history associated with it. Using the word to refer to black people is insulting due to this history. Try to educate yourself on the word before using it so care free.
