Rickrolling is an Internet meme involving the music video for the 1987 Rick Astley song "Never Gonna Give You Up." The meme is a bait and switch; a person provides a hyperlink which is seemingly relevant to the topic at hand, but actually leads to Astley's video. The link can be masked or obfuscated in some manner so that the user cannot determine the true destination of the link without clicking. People led to the music video are said to have been rickrolled.
