A music genre popularized in Brooklyn in the early twenty-teens in which spirited, if not talented, bands celebrate the work of others through hard-charging covers. Good for drinking, fighting and singing along.
Examples: Rolling Stones cover band Mick's Jaguar. Pink Floyd cover band Chink Floyd. Japanese quintet The Hard Nips.
There was a hatchet rock showcase at the Merc last night. I got wasted and sang along to GnR tunes.
