Any Metal Sub Genre that Ends With the Word 'Core' 

There are more than enough, and possibly way too many, of these mindless sub-genres to list right now, but allow us to attempt it anyway.

Crabcore: Same ol' metal music, except the genre is defined more by the band's strange behavior than the music itself. All the guitarists squat down in this odd position, which is--you guessed it--supposed to make them look like a crab. Thank you, Attack Attack for the stupidest musical genre that's ever been created. Watch their 'revolutionary' video here.

Then there's hardcore, horrorcore (a black swamp of lyrical themes that includes everything from sadism to suicide), metalcore, deathcore, and other 'core' worms that we'd prefer to leave in the can, thank you very much! The only exception? Mathcore. It actually requires some serious technical precision and skill, so fly free Mathcore. But remember, you only get one 'Get out of Jail Free' card in our game of music monopoly.
