What is it?
An internet prank or joke. Rick Roll, Rick Roll'd or Rick Rolling is an internet spam trick in which people post a link to a Rick Astley video on YouTube, but say the viewers of the video are being led to another video, usually proof of unconfirmed gaming news or trailers.Pretty funny page
Here's another def:
When someone sends you a link of a suspected you tube movie that seems to be interesting, but when in fact it is a music video of a guy named rick dancing to a catchy tune.(This last def comes from the PopUp Video version, which I always love!
If you like 'Never Gonna Give You Up' at all, or are open to it, you should click through on one of these links to enjoy the full effect. It'll make you smile :-)
