One's anal passage.

Mud, a synonym for shit, and Vayne, which stands for the backpassage itself.
Man, eating at Taco Bell three nights in a row... my mudvayne is going to wreak havoc tonight!

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.

a really good band with some very talented musicians in it. Spag and Ryknow are probably the msot noticable. And they are not called math metal because they sing about science and pills. they are called math metal because they weird time signatures. I read it in a magazine. I cant really explain it...but it doesnt have any thing to do with science and pills.
Mudvayne is a really good band

An amazing NEW metal band, not a nu metal band fronted by Chad Gray, the only new rock vocalist who acts like a rock vocalist should: Fucked in the head . They used to wear kickass makeup but they got rid of it do to the Slipknot (BOOO!!!!) comparisons. Their sound is all about frenzied, insane-sounding vocals with some crazyass bass lines and distorted guitars.
Mudvayne is the shit and Chad Gray belongs in a looney bin.
