Other words that a faerie (Like Tinkerbell) Would use?

[Naruzeldamaster]

In my story these Faerie are quite intelligent, some of them are even linguists and write books for other species in my story.
But, as intelligent as they are, when they're angry/flustered, they will often resort to 'faerie like' vocabulary.

For my story as it stands:

Nincompoop in place of 'stupid' is a big one.
Ninny is another one. (Debating on if it means something different for the faerie folk or if they use it the same way the other species do)
Lemming is used occasionally for people/adventurers who blindly follow orders.
Yellow: Besides talking about the primary color, it's particularly faerie slang for being a coward. And yes, yellow, not yellow bellied.
Etc.

For me the last two feel too normal and based in this world to be Faerie words
If we are talking Tinkerbell, I feel theri words should be more musical or whimsical or even straightforwardly comic.
I like "nincompoop", because it has the world "poop" in it.
And "ninny" because it sounds gentle, reproachful without being mean about it.
