Citizens Understand Medieval Games Undermine Loving Parents (CUMGULP) is an activist group in Grand Theft Auto IV. The group's goal is to outlaw all video games after the Dragon Brain massacre, in which a Chris Ryan had murdered someone after a showing of the film. Its name is another example of Rockstar's humor, and references the act of swallowing cum.
