A vocal style originating in late 1980's involved with underground grindcore/Brutal Death Metal bands. The style is usually used by either inhaling or exhaling while coarsing your throat to either sound like a high pitched pig squeal, or a low pitched gurgle. Pig squeals have now become a style that is seen more in the light now due to hardcore/metalcore bands that have been recently becoming increasingly popular.
