There's a ton of things Chachan isn't good at. However, if I had to specify things that he isn't good at and yet he tries anyway... it's probably a toss-up between "being mature" and "laying down the sick burns." Maybe "lying" as well. After all, the fact he's Doman is pretty much not a secret at all at this point, and most folks are skeptical when he says he's 19.
The latter is what leads to the whole "failure at acting mature" angle. He has his moments, sure, but with his boundless, childish energy along with his penchant for pouting and getting fussy when things don't go his way... it's hard to consider him as anything other than immature.
Also, when he gets into arguments that descend into insults, he totally tries to act like how he saw Ser Crofte did that one time in the Quicksand. He just ends up being really bad at it. Getting flustered when his opponent is more mentally dextrous when it comes to such things doesn't help matters either.
Maybe that's why the fights between him and Koporo go so well. They both equalize onto roughly the same maturity level...
