Seriously though, this guy.
They got their name because the singer, Fred Durst (pictured) wanted a name that was as easy to say as "Led Zeppelin", other than that he was very not picky. Google the names they considered. They're horrible.
Coming in strong in the nu-metal/rapcore scene, these guys managed to alienate another band who was a major name with Durst's trash talk during one show. Talking about how all of Slipknot's fans were "a bunch of fat kids" he got a whole pile of their own fans ticked at him since he had a mountain of mutual fans. Basically, he's a moron.
Still though, their music can be kinda catchy, which is why I enjoy them at times.
Of course I would pick the one song that everybody knows to post though. Ah well.
