A play on the terms hardcore, deathcore and other sub-genres of heavy metal music with the suffix 'core', fagcore describes music made by untalented hacks trying to pass themselves off as serious musicians. Commercially-motivated, most fagcore artists are teen and mainstream orientated.
Linkin Park, Jesse McCartney, Yellowcard and Fall Out Boy are arguably some of the most prominent fagcore artists.

Sentence usage can be as follows:
"Linkin Park is nothing more than fucking fagcore crap."
