Horrorcore, also called horror hip hop, horror rap, death hip hop, death rap, or murder rap is a subgenre of hip hop music based on horror-themed and often darkly transgressive lyrical content and imagery. Its origins derived from certain hardcore hip hop and gangsta rap artists, such as the Geto Boys, Gravediggaz, and Three 6 Mafia, which began to incorporate supernatural, occult, and psychological horror themes into their lyrics. Horrorcore is mostly designed to evoke fear and panic out of a listener rather than disgust. Unlike most hardcore hip hop and gangster rap artists, horrorcore artists often push the violent content and imagery in their lyrics beyond the realm of realistic urban violence, to the point where the violent lyrics become gruesome, ghoulish, unsettling, inspired by slasher films or splatter films. While exaggerated violence and the supernatural are common in horrorcore, the genre also frequently presents more realistic yet still disturbing portrayals of mental illness and drug abuse. Some horrorcore artists eschew supernatural themes or exaggerated violence in favor of more subtle and dark psychological horror imagery and lyrics.
