Does it matter that my Panty Shot is Naughty?

I'm on my quest to defeat the Dark Lord, and specifically this time I'm bringing the legendary merc Panty Shot along for the ride. However, he appears to have spawned with the "Naughty" modifier:

(Yes, that is his name. No I did not pick it.)

I've had a few odd adjectives applied to some of my companions before. For instance, my King was once Masochistic. This seemed to give him the chance to... exclaim, let's say, when he was hit. Some of the other adjectives are obvious, like "frail." However, I can't figure out what "Naughty" does. It doesn't seem to do anything, as far as I can tell.

This is all complicated by the fact that I'm naked. (Zenura Weave FTW) I'm a bit uncomfortable with Panty tagging along with my lady bits hanging out. Can someone tell me if there's something I should be worried about here, or am I just being paranoid for nothing?
