Sergeant James Doakes, played by Erik King in the television series Dexter, which premiered in 2006, became famous for repeatedly saying the line to Dexter Morgan. Clips of Doakes confronting Dexter were cut into short reaction videos and remixes online, and the phrase turned into a standalone meme for any unexpected arrival. Its popularity survived beyond the show because the delivery is instantly recognisable, very short, and easy to place over films, games and real life footage without needing context from the original scene.
