Cargo Ship: Due to his habits of collapsing and rolling around on the stage during lives, some people jokingly ship Yoshiki with The Floor.
Estrogen Brigade: Yoshiki, unlike most heavy metal/hard rock artists, has a sizable female following.
Fan Nickname: "Yo-chan" (bestowed by hide, who was arguably one of his biggest fans as well as his guitarist), "Yoyo" by fans, "¥o$hiki" by Fan Hater, "Pony" by people who think his face looks pony-like, and "Princess" by Brazilian fans and fans elsewhere.
Funny Aneurysm Moment: Yoshiki would often fake falls and collapses in shows for the sake of drama and showmanship. When he collapsed for real from his neck injuries in 1996 and 2008, it was written off by some as drama and fanservice.
Hate Dumb: A fair amount of the hate toward Yoshiki is either misaimed or over things he can't do anything about, and a fair amount of it is haters simply jumping on the bandwagon of who's popular to hate.
Internet Backdraft: There are so many ways to start Internet Backdraft related to Yoshiki that it would take its own page. Suffice it to say that unless at least some other people are talking about him favorably or no one around knows about him at all, and even then on some occasions, even mentioning him will lead to immediate Internet Backdraft.
Memetic Mutation- The aforementioned Rice Monster, which he still hasn't quite lived down.
Misblamed: Some of the concerts were canceled for reasons beyond his control, and the miniature scandal that was the Photoshopping and announcement of 8000 fans for the promotional video shoot was due to the graphic designers and PR people involved.
Took the Bad Film Seriously - Yoshiki doing the music for Saw IV and for Repo! The Genetic Opera. Yeah, one of the once-top drummers in the world, who *could,* had he gone classical rather than rock, be a virtuoso pianist, who created and led one of Japan's most successful rock bands, who is an extremely talented musician....working for people who, in the case of Repo, couldn't even pronounce his name correctly. Not to mention these movies are no Oscar bait (Repo actually even won Razzies)
Don't know about Saw, but Repo! was never meant to be Oscar bait (it was very much a culty low-budget pet project, and the Critical Dissonance around it has to be seen to be believed), and the Razzie was a bit unfair (Given to Paris Hilton seemingly just for being Paris Hilton, because her performance was perfectly fine). And it definitely wasn't a bad film- just a very creative and unusual one that won't be to everyone's taste. And nobody in North America seems to be able to pronounce anything Japanese without making a pigs ear of it, although yeah, how the Repo! team managed to carry on doing it for six months without realising is anyone's guess.
