It's dumbed-down metal and hardcore with a lot of emo to it. As I Lay Dying, Bullet For My Valentine, It Dies Today, every single band on Trustkill...yeah. A lot of the bands that Metal Blade and Century Media have been signing for the past 5 years are extremely fashioncore, as well. Walk through a mall and be sure to pass by the Spencer's Gifts and Hot Topic areas, as well as the food court (usually near the Sbarro's or the closest door to go out into the parking lot), and just look at the majority of the bands that the kids in all black (ie. mallgoths) have on their shirts. Every now and then there'll be a Metallica, Black Label Society, Slayer, or obscure death metal band, but most of the time it's some fashioncore group that is "so brutal and hardcore" until the end of the week.
And J0b, all of Nile's albums have the Middle Eastern feel to them. That's their gimmick: Egyptian death metal from North Carolina.
Back in my day, we called them posers.
