I'm going to call my friend a racial slur
Why would you call a good friend a racial slur?
I just want to see his reaction.
It's wrong to use racial slurs on people, especially a friend. You will just hurt their feelings and they won't want to hang out with you anymore.
This is like doing an experiment, I do not think he will mind.
I think your friend will mind. Racial slurs are inappropriate and derogatory. These words should not be said.
