Well I did, and I just knew that Youtube is secretly very in love with Rick Astley because all the videos on that day were his "Never Gonna Give You Up."
At that time I didn't know the term Rickroll yet.
Until today I got notification that YouGotRickRolled is following me on twitter, and when I click the url on its Bio, voila....there he is again Rick Astley is shaking his hips and singing that Never Gonna Give You Up :))
So what is this Rickroll about?
Rickrolling is an Internet meme involving Rick Astley's music video for his song "Never Gonna Give You Up". In a Rickroll, a person provides a link they claim is relevant to the topic at hand which actually takes the user to the Astley video. It can also mean playing the song loudly in public in order to be disruptive.
The practice began as a variant of an earlier prank called duckrolling, in which a link to a popular celebrity or news item would instead lead to a photoshopped picture of a duck with wheels. By May 2007, the practice had become widespread, and it eventually began to receive some coverage in the mainstream media.
