Rickrolling or a Rickroll, is an internet meme involving the unexpected appearance of the music video for the 1987 song "Never Gonna Give You Up", performed by the English singer Rick Astley. The video has over 1 billion views on YouTube. The meme is a type of bait and switch, usually using a disguised hyperlink that leads to the music video. When victims click on a seemingly unrelated link, the site with the music video loads instead of what was expected, and they have been "Rickrolled". The meme has also extended to using the song's lyrics, or singing it, in unexpected contexts. Rick Astley has also been Rickrolled on several occasions.
