Rickrolling is an internet bait-and-switch prank built around Rick Astley's 1987 song Never Gonna Give You Up. The meme became widely known in the late 2000s when disguised links redirected people to the music video instead of the promised content. Since then, the joke has spread across forums, social media, livestreams and short-form edits. People still use it because the song is instantly recognizable, lighthearted and easy to drop into a reveal. It sits alongside other long-running internet joke sounds like Trololo.
