One's anal passage.

Mud, a synonym for shit, and Vayne, which stands for the backpassage itself.

A pathetic hack typical nu-metal band named after your poop chute. Most often seen in ridiculous makeup & costumes (similar to Slipknot's mask/jumpsuit gimmick) because they're as embarrassed to be playing that crap as you should be for liking it.
No matter what you try to tell me that "Mudvayne" stands for, it's just a 'kewl' re-spelling of "mud vein", which is your rectum and asshole. The band is named after something shit comes out, which is appropriate since the only thing I've heard from them is also pure shit.

One of the worst bands today. The only good album was L.D. 50, before Chad Grey started screaming and ruining every good song that they've made. The only acceptable songs are "-1," "TV Radio" and "All That You Are". Of course, the last one ruined by Chad's nasty screaming.

It also has fans saying stupid shit like "Mudvayne alone is a sentence if you understand the definition." It's one word, that doesn't make a sentence.

They also decide to dress up as ugly f!cks on stage, as that's the only way they can get people to look at them. Recently, Chad Grey has taken vocals in Hell Yeah where he actually sings pretty good, and his screams aren't so bad that they make your ears bleed.
Chad Grey of Mudvayne shits on everything he does.

When an emo person thinks they're not "hardcore" enough, they get a chip on their should. Then, they start doing too much heroin, have spiderveins, and cover their faces with a mask, become a shitty band, knowing nothing of music, and pretending the noises they make are "mathmatical"
Wow guys... you look like Mudvayne, but you're going to have to drop the record frame glasses.
