I'm going to hang up on my friend for being a sexist douche
Why? What did he say that made you think he's a sexist?
I'm tired of his pussy ass attitude and I'm tired of his shit.
Its pretty mean to hang up on a friend, but it makes sense that you are angry. Just by how you are talking it is apparent that your friend is getting on your nerves. Talking to your friend about this seems like a good idea, but if they continue to do it then you may need to distance yourself a little for your own sanity.
Me talking to him about this isn't going to resolve anything? I want to show him how bad it feels.
I do not recommend you retaliate and be rude towards him as the only result of that would be him also being rude to you. I would tell him that he shouldn't say sexist remarks but also try and tell him why it is hurting the people that he is saying those remarks to.
