Dirtcore 

A musical genre infusing extreme metal with elements of grunge, creating some of the most pure awesome rock on the face of the planet. Imagine grindcore/death and grunge, that's what I'm going for, it could be very tasteful if you think about it. Like Killswitch Engage on musical steroids.

Dirtcore: Like Killswitch Engage on musical steroids.

DictCore 

Bands that when looked up on Urban Dictionary have positive definitions, though the bands are absolute shit.

Pierce the Veil, Asking Alexandria, and BFMV are DictCore.
