Massacration is a fictional American heavy metal band created by Brazilian humorists and musicians Bruno Sutter, Fausto Fanti, Marco Antônio Alves, Adriano Silva and Felipe Torres, all of them part of the comedy troupe Hermes & Renato. Heavily influenced by the similar semi-fictional metal act Spinal Tap and self-styled as "a banda da galera", Massacration is a light-hearted parody of heavy metal subculture and "metalhead/headbanger" stereotypes, lampooning the music and aesthetics of such famous metal bands as Black Sabbath, Iron Maiden, Judas Priest, Manowar, Sepultura, Angra, among others. The band's music features humorous lyrics written in a combination of intentionally broken English and Portuguese, sung in an exaggerated falsetto by Sutter.
