"Here's Johnny" comes from Stanley Kubrick's 1980 film The Shining, shouted by Jack Nicholson as Jack Torrance during the movie's most famous door-breaking scene. The line became one of the best-known quotes in horror cinema and later spread widely through meme edits, soundboards and short video remixes. It remains popular because a two-second clip can instantly communicate menace, surprise and over-the-top comedy, especially in entrance gags and fake jump scares.
