4. Pink Flamingos (1972)
Director: John Waters
John Waters is one proudly depraved human being, and he came into the public consciousness with his colorful and twisted comedy, Pink Flamingos. Starring drag queen icon Divine, the movie tells the story of “the filthiest person alive” and we follow one disturbing exploit after another. During the course of the picture, Waters assaults our basic human decency with any number of perverse sexual acts and moments of the grotesque.
This movie doesn’t land on this list because of scenes of violence or torture; instead, this is here because of its depiction of incest, cringe-worthy nudity, and the ever-so-famous moment at the end where Divine proceeds to eat a pile of dog feces. But despite this, Pink Flamingos has managed to become an underground cult sensation over the years. We just don’t suggest watching it within 24 hours of eating.
