<p>I've seen this curled-up tongue trope pop its head up every once in a while and I was wondering: Which trope is it, and where does it originate from? </p>

I think this so-called "trope" is only unique to the author of the manga. I don't believe that it's actually a common recurring trope in manga or anime.

This might be completely wrong, but I think this face/trope is more about the wide-mouthed grin rather than the curling tongue.

Compare it to the emoticon ":V", which is usually used online after saying something that will annoy the reader. Which is what is also happening in the panel given in the question.

Example:

**Person A:** You should watch Avatar, It's one of my favourite anime second only to Lucky Star.

**Person B:** I'll check it out, but technically Avatar is a cartoon :V

They seem similar enough both in what they represent and how they look to be connected.
