The line comes from the post-credits scene of the 2016 Deadpool film, where Ryan Reynolds as the Merc with a Mouth addresses the audience directly after the story has finished. It parodies the famous ending of Ferris Bueller's Day Off, in which the hero tells lingering viewers to go home. Clips of the moment spread through YouTube edits, reaction videos and soundboards, where creators reuse it as a knowing sign-off. It remains popular because it instantly signals the end of something while keeping Deadpool's irreverent, self-aware humour intact.
