usually a cheaply-made sub-genre film (usually in the horror genre) designed for the teenage audience (teen movie), deliberately made to contain gory, blood-splattering, explicit deaths without any build-up, style or suspense, often committed by an unstoppable serial killer, with a sharp bladed weapon; most slasher films are created to generate sequels and repetitive boredom; aka splatter films; see also trash film, grindhouse film, schlock film, B-film and Z-film
