Grind house, a term popularized in the 1960s, is a type of movie theater that specializes in showing low-budget films featuring sex, violence, and gore. Some synonyms for these types of movie theaters include exploitation cinema, trash cinema, sleaze cinema, and horror cinema. These movie theaters are notorious for showing films with explicit content that many mainstream theaters refuse to screen. Many grind houses were located in urban areas and were popular among young adults and college students. Today, many of these films have reached cult classic status and have influenced modern-day horror and thriller genres.
