I'm going to say nigga around my black friend who clarified he was okay with it
Why do you think you need to say that term to him?
Yes, I know him for a while. He's really cool
That is an offensive word and it is wrong to say it. You will offend people saying hurtful things.
I don't give a fuck. It's not like he's an A.L.L.I.E. who would shut me down.
You should care about what you say to others and how your words can mean harm to people even if you don't mean to do so. I suggest you do not use that term as it can be seen as something derogatory and it is very inappropriate to say even to your friend.
