The line comes from Steven Spielberg's 1993 film Jurassic Park, adapted from Michael Crichton's novel. In an early scene in Costa Rica, computer programmer Dennis Nedry, played by Wayne Knight, meets Lewis Dodgson from the rival Biosyn company to arrange the theft of dinosaur embryos. Dodgson wants discretion, but Nedry mocks him by announcing his name to the whole cafe. The moment became a lasting meme template online, shared as a reaction for exposing, greeting or loudly identifying someone in public.
