When you hear musical feuds, you think of Nirvana and Guns n Roses. Metallica and Megadeth. But not Smash Mouth and Third Eye Blind!

Well apparently these bands hate each other and their long rivalry continued this past weekend at the BottleRock Festival in California.

The Washington Post is reporting that while both bands had competing sets at the show, Smash Mouth singer Steve Harwell said to the audience, "Third Eye Blind can suck my d**k." (I think you know what those two letters are.)

This has been going on for a long time but Smash Mouth's manager tried to make it sound like it wasn't a big deal. He told The Washington Post, "Steve pretty much has a long history of poking fun at Stephan Jenkins. There's no true bad blood there. They've toured and done shows together for quite a while. You know, he pokes at (Jenkins) and now that he's got his former guitar player in a side project, he wanted to poke a little harder."

Maybe it's just me, but when you go on stage in front of the Smash Mouth faithful and tell another band to "suck my d**k", that doesn't sound like the guys are just joking around.

Your move, Stephan.
