Gorilla Metal
Metal music that sounds like what you'd get if you put a bunch of gorillas behind some instruments. Usually described by gatekeepers as "real metal." It is essentially the metal version of butt rock, but significantly less commercially accessible. Gorilla Metal can quickly be identified by the use of 7 and 8 string guitars to make up for a lack of creative writing ability, tasteless drumming that consists mainly of smacking the kit as loud and frequently as possible, and mainly screamed vocals. If there are clean vocals, they are certainly autotuned garbage.
