Emo stands for emotional hardcore. Anyone who denies that obviously have no facts. Rites of Spring started emo, and it was bastardized by the media when Get Up Kids went big and changed to powerpop. Thus, emocore is proving nothing.
Often times, emocore is placed on Thursday and A Static Lullaby along with the label screamo. Screamo is actually a style of music started by bands like Orchid and perfected by bands like Fueral Diner and Joshua Fit For Battle. Anyways, both bands have constantly explained how they are NOT emocore and dislike this label. Especially ASL, they will yell at their crowd about it.
Please, correct yourselves.
Considering it's constituents, presumably this means cutting oneself with a chainsaw instead of a razor.
When one is emocore, these are exchanged for chainsaws, running circular saws, and metalworking equipment
