I predicted there was going to be another Waluigi thread with a rhyming word, but I didn't expect the post to be making stuff up. Maybe it's better suited for a Forum Games topic, just to see what people can come up with that involves Waluigi. I don't care for the guy, I remember there being a lot of hoopla over him in Mario Tennis for being new and always staying close to the net (which made it easier and more satisfying to smack him in the nose with the tennis ball), but after that I wasn't aware he was even appearing in anything else. I just forgot about him.
But I have a theory that if you take some Waluigi thing and replace it with Wario, people will like it more. Change a Wario thing to Waluigi, and people will hate it. Maybe Wario just has a better manic grin.
Oh, and for the "purple != gay" thing in that other topic, I've known a few characters in cartoons that wore purple or pink and were great. Their choice of color didn't seem to matter (Br'er Rabbit from Disney's "Song of the South" wore pink). There are exceptions, sure, but it doesn't automatically imply anything.
