Rickrolling is an internet bait-and-switch meme built around Rick Astley’s 1987 song Never Gonna Give You Up. The prank became widely known in the mid-2000s when disguised links would unexpectedly open the music video instead of the promised content. It spread across forums, social platforms and video sites because the song is instantly recognizable and harmlessly cheesy. The meme still works because audiences know the setup, so the humor comes from the reveal and the shared recognition.
