The act of following a link which you believe to be a subject of interest for you but instead links you to a video of Rick Astley - Never gonna give you up.

A recent developed term that pertains to a user being tricked and led to a youtube.com video produced by "cotter548" which directed users to the music video of "Never Gonna Give You Up" by Rick Astley.
A person will try to trick, or "rickroll" you by means of displaying any false information, or commonly a false "video" that shows interest to the community; deception.

The term was developed by users on forums that have located the video and have known that is has no particular value or even remotely related to the game/community which is directed to develop anger by the user who clicks the link.

"Rickrolled" is a fruition of the earlier word, "Duckrolled" which is the same meaning of deception.
The practice of tricking people into viewing this song is called the Rickroll, trolls who do it are called Rickrollers, and people who are tricked by this are "Rickroll'D" or "Rickrolled"

This term and practice is being spread out mainly by the gaming community and by online forums. Usually a user may announce a video that has probably been leaked or a video that has value to the community; when the link actually leads them to the same video created by "cotter548" called "Rickroll'D" or "Rickrolled."

In due time this term may cause conflict among forums; due to false information spreading out coming into conflict with true information; or by means of "The Boy Who Cried Wolf."
