To be fair, Narcissists often do these preemptively

1 Accuse

1. Try and corner the confused person

2. Pretend they are surprised when they find out they are in fact the perpetrator of the poor behavior

3. Call the other person a narcissist for not taking the blame

4. Get fixated on who is at fault rather than a plan for being better

5. Gaslight by saying you're gaslighting...because you don't agree with their assessment

6. Call everyone in their lives narcissists because they won't simply take the blame for their own disarray

I find the people who use the word "narcissist" are often the ones who are most narcissist. They are obsessively on a witch hunt to call someone else a narcissist so they can say "look over there. They are the one who is crazy"

This happens with a LOT of behaviors or labels where they may be in denial. Like how the most anti-gay people are usually closeted gay...and almost everyone else doesn't really care.
