A bad metal band that tries too hard to be "hardcore metal" or "metalcore" or whatever you call it while sucking in the process. News flash: Constant, incoherent screaming doesn't make you a "badass", it makes you look like a group of idiots with no depth. I'm not saying they aren't instrumentally talented, because they are, but raw talent and manufactured guitar solos don't make up for shitty songwriting and boring concepts. Similar cases of talented bands that still manage to suck include Dream Theatre and Children of Bodom.
"YEAH! LAMB OF GOD IS TEH HARDKORE!!!1"
"Lamb of God could be so much better, but they choose to be fucking lame."
