countrycore 

Metalcore with a southern rock twist on it. Bands include, but are not limited to: Every Time I Die, Once Nothing, and Maylene and the Sons of Disaster.

Countrycore concerts aren't for swag fags or scene kids, as they can get pretty hardcore and feature a lot of moshing and broken bones (bring Ibuprofen or Tylenol).

"Dude, did you go to that Every Time I Die concert last night?"

"Yeah, man! I felt so fucking countrycore when they played 'Partying is Such Sweet Sorrow.' I ended up punching a scene kid in the face while I was moshing."
