[He won't laugh!! Katsuki's trying to be better at being less rude, so he shakes his head and keeps a straight face. No laughing!!]

I... have no idea why we call 'em that. I think it started because it sounds catchy, and now it's been long enough that it's the scientific term for them.

[Katsuki stomps out a tiny fire he comes across on their way, as he talks about that. Their world is... weird. And he's very aware of it.]

It's just first nature now to call super powers "Quirks" even if it makes no sense. But I'm trying to switch, goddamn it.

[ITS HARD... but he doesn't want to confuse people while talking about powers or have to explain what Quirk means to multiple people. It's already annoying how many times he's done it this far, but he only has himself to blame.]

As for the powers I'm interested in? "Immunity to freezing". That would really help me out, considering my Quirk is all based around me sweating. I tend to be slow at getting started when it comes to cold temperatures, because it takes a while for me to actually get sweatin'.

I have a feeling if I was immune, I'd be sweating up a storm in any weather.
