shitty excuse for metal music. Formed from a deformed asshole from which NASA had never seen before. Once opened, the shittackular music spewed through the anal leakage which formed shitty bands like as I lay dying and unearth.
-Did you hear that new local band?
-Yeah, they're Metalcore, they might as well have cookie monster for their vocals. It's not like you can call them a singer or a band all together

One of the best genres of metal there is in my opinion. Originated in the late 80's. Cross between hardcore metal and hardcore punk. A lot better than shitty nu-metal.
Metalcore bands include the OLD avenged sevenfold, OLD atreyu, underoath, lamb of god, killswitch engage, bullet for my valentine, as i lay dying, some black dahlia murder, all that remains, some machine head are some of the more mainstream stuff. a good unknown band is august burns red.

a non exastant form of music. there is no such thing as "metalcore" however, there is such a thing as punk faggots trying to play metal while not admitting to liking metal and using the terms "hardcore" and "metalcore". people who subscribe to this stupid fucking term are morons who need to be killed. also see, THERE IS NO SUCH THING AS A GODDAMN "BREAKDOWN", only such things as, untalented solo riffs...... minus the solo
FUCK anything "core". it is non existant and needs to be killed. i need to help kill it. there is punk music.... and there is metal.... there is also faggot ass punk fucks trying to be metal. THE FUCKING END. oh, and go to gigantour everyone
