Mainstream rock music that is corporately controlled, and usually a cynical attempt to cash in on hit mainstream trends. The word comes from the music being played in terrible mall stores like Hot Topic. Peoples' main problem with mallcore is stupid tweens and teenagers acting like it's the hardest, most badass rock in the universe and the record labels promoting it as such. Usually, it refers to the genres of nu-metal, metalcore and post-grunge. While good bands do exist in these genres, mallcore refers, frequently, to the most grating, stereotypical and shitty examples.
