Pornogrind, also known as porno grind, porno-grind or porn grind, is a musical subgenre of grindcore and death metal, which lyrically deals with sexual themes. Natalie Purcell's book "Death Metal Music: The Passion and Politics of a Subculture", suggests that pornogrind is defined solely on the basis of its lyrical content and unique imagery, its focus on pornographic content. Purcell notes that bands like Gut include "simpler, slower, and more rock-like songs". The artwork for pornogrind bands' albums is noted for its extreme and potentially offensive nature, which "would keep them out of most stores". an example of the genre is Cock and Ball Torture.
