Rickrolling uses Rick Astley’s 1987 song Never Gonna Give You Up as the payoff to a bait-and-switch link or reveal. The prank became widely known online in 2007 after users redirected people expecting unrelated content to the song’s music video. “Do not touch” versions add reverse psychology by presenting a button or object that invites curiosity. The format remains popular because the opening is quickly recognized, the joke needs little explanation, and it can be adapted to messages, videos, games, streams, and presentations.
