octanecore
Octanecore is what happens when a metalcore band tries to be popular and fails. It's the music you hear when your dad starts listening to metalcore again. It's like butt rock, but it's for people who think they're in a band.
'I can't stand this octanecore, it's like my brother's failed rap career.'
Tweet: 'Octanecore is the reason I now hate my radio.'
DM: 'Why are you listening to octanecore? That's just metalcore for people who can't do math.'
