Showboating is alright as long as it's in good fun. If you're being a prick when you showboat, like Tito does, it's funny but it's also pretty f**ked up. I don't like Rashad at all but I think he was doing those Muhammed Ali moves in his first fight out of nervousness. I don't think he was trying to do it to showboat cuz it was always after he got hit really hard so my guess is it was just like a Forrest Griffin twitch except instead of hitting himself in the forehead 1000 times he does the Ali thing. I didn't see it as showboating, I just saw it as a way he deals with pain and getting himself pumped up. If he was doing it to showboat, then he woulda done it after HE hit his opponent, not after he GOT hit by his opponent.
Terrel Owens type showboating
Chad Johnson type showboating
