To not only be overlyfascinated with oneself, but to also inject conversations with large doses of sardonicism.
"Look, i know you are utterly self-obsessed but do you think you could take your sarcasm some place else? Your narcastic attitude isn't welcome here, you rat bastard!"
To act in an extremely arrogant, miserly fashion, and to be condescending onto religion, also to be obsessed with the TV show "Naruto". To act narusistically, would also mean to be unforgiving, and to disrespect a certain aspect.
In the Context that some-one punches another we could say
"Jack narusistically declined the apology"
Or in the context of arrogance
"Jack's narusistic behavior towards the Christians, made them both enraged and angry"
