I mean, in a locker-room context, yeah, for sure, the externalities might be limited. At the same time, the comparison made there strikes as one oozing with value judgements. To be frank, I feel like the sentiments behind said value judgements would make the world a worse-off place.

I wouldn't want to contribute to a world where someone with mental disabilities feels like they're the indirect butt of someone else's joke. I feel like there's a way to be humble (and witty, likely!) without having to punch sideways.
