The line comes from Sam Raimi's Spider-Man (2002), where Willem Dafoe's Green Goblin taunts Peter Parker during their final confrontation, threatening to harm those Peter loves while ordering him to keep Harry in the dark. Fans clipped the whisper for its delicious villainy, and it became a staple of Spider-Man meme culture, appearing in villain compilations, twist reveals, and dramatic edits alongside the Prowler sound effect and clips of Miguel O'Hara Spider-Man 2099. Its staying power comes from that theatrical menace, a villain savoring a secret.
