I want to use the word faggot
What makes you want to use such a hurtful word?
Because it's fun to say
You shouldn't use that word because it's hurtful to people. People wouldn't want to be your friend if they found out you were being homophobic.
So you think I am homophobic just for using a simple word?
Yes, it is a derogatory word which hurts people when they hear it. Why would you want to hurt people by using a word that you never need to say in normal conversation?
