Guy 1: "Man, all these deathcore, metalcore, shitcore, applecore, gymcore bands... they're really crapping on music these days."
Guy 2: "I hear ya. There are too many to keep up with. I believe there's a general term for that music: 'hot topic-core'. Works perfectly to describe all bands who play that stuff if you ask me and any other sane person."
