Any one of a number of indy bands who, to compensate for the fact that they have no musical skill, ability, or talent, add the suffix "core" to the end of a random word to create a "new genre" that justifies their suckage. They can be found playing 20-band-shows for the other bands and their girlfriends and talking about how their "genre" is "misunderstood"
Antonym: Actual-core. See "Psyopus".
