GWAR frontman Oderus Urungus slammed HELLYEAH during his group's April 25 performace in Buffalo, New York, calling them "fat, dumbass, tattooed ignorant, inbred fucks" and making fun of HELLYEAH's band name.Before Oderus and his bandmates launched into "The Uberklaw" from their 2009 album, "Lust in Space", the frontman addressed the crowd with the following tirade (see video below): "How 'bout that new HELLYEAH record? Pretty good, huh? What a great name for a band — Hell, yeah. That is so awesome. How did those fat, stupid dudes from Texas ever come up with something so awesome? How did those fat, dumbass, tattooed, ignorant, inbred fucks ever come up with such an amazing idea as HELLYEAH? Wow, Stephen Hawking, move over! Hahahahaha!" The next day, the members of HELLYEAH themselves responded via Twitter, writing, "We"d like to thank Gwar's lead singer for talking shit about us at one of their shows. Classy guy...yay you!" HELLYEAH singer Chad Gray added earlier today, "I don't know what all the hype is on this gwar thing. I think it's an honor to be ripped on by gwar! They're awesome! Thanks oderus!"
