nadada - Nadada is when you're too cool to say no, but you still say

Nadada is when you're too cool to say no, but you still say it in a way that makes it clear you're the best and everyone else is just annoying.

'Nadada, I'm too cool for your little drama.'

'Nadada, I'm not even annoyed, I'm just better than you.'

'Nadada, I'm not going to your stupid meet-up.'
