two things:
first, this past week I finally learned how to pronounce the word "portmanteau". I've somehow never heard anyone actually say that word before, and it sounds so weird when spoken.
second, I learned that Wario is not, in fact, canonically related to Mario in any way, rather they were simply childhood friends turned rivals. that makes it even weirder that Wario dresses so similarly to Mario, like what's going on there lol. not to mention Waluigi isn't related to Wario either, the way that they dress lowkey comes across as some kinda obsession thing haha (though I guess in canon Waluigi has been shown to be a bit of a stalker, he's a creepy string bean sometimes).
doesn't bother me though, Wario and Waluigi are hilarious and iconic
