How do I make a narcissist angry?

I am considered narcissistic by many classmates, and whether or not I am, nothing they can say can really anger me. I generally don't care what they say - that doesn't mean I'm a rude *****, though. I'm naturally like that. Narcissists can either not care what you think, may believe you are jealous of anything of theirs, etc etc. Perhaps you can try to prove them wrong in some way, such as in a debate. That'll prove they aren't as great as they thought they were in everything, or whatever.

Look at yourself in a mirror.

Are you angry now..!

Insult what he likes.

point out their flaws
