Does your narcissist have a sick smile they give out when they do something nasty or otherwise? Different from usual smile

So I had a huge fight with my Ndad the other day. Before fighting with me he fought with my mom and he in middle of fight started gaslighting her.

Catching lies and gaslighting is easy when not directed at you.

So I did catch it

Then he started fighting with me and fortunately enough I caught his gaslighting and lies

Then I got even more angry and confronted him not just the lie he told me but also the one he told my mom. Now when I did he gave this creepy smile like which said "Aren't I intelligent?" "Look how smart I am"

And he does when he thinks that he's a winner in sense that other person didn't catch his lies

Anyone else?
