The Rickroll comes from Rick Astley's 1987 song Never Gonna Give You Up, which became a famous bait-and-switch prank when a promised link instead played the music video. This version was created by Konoaru during a game of SCP: Secret Laboratory, when seven random players on Discord joined in and sang it together. That spontaneous, multiplayer origin is part of its charm, and clips like this keep circulating because the prank still works: the melody is instantly recognisable, while the unexpected group performance makes an old joke feel new again.
