I had already told Sheri I was going to do this so for all to understand what being "rick roll'd" is. This is something that started in 2007.
Rickrolling is an Internet meme typically 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 web link that he or she claims is relevant to the topic at hand, but the link actually takes the user to the Astley video. The URL can be masked or obfuscated in some manner so that the user cannot determine the true destination of the link without clicking. When a person clicks on the link and is led to the web page, he or she is said to have been "Rickrolled" (also spelled Rickroll'd).
It is not fun for those that have had it happen to them because it completely freezes everything on the computer until the song ends.
