Ok, time for some posting.
Do you know what Rickrolling is? No? Well, read on!
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 hyperlink that they claim is relevant to the topic at hand, but the link actually takes the user to the Astley video. The link 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". Rickrolling has extended beyond web links to playing the video or song disruptively in other situations, including public places; this culminated when Astley and the song made a surprise appearance in the 2008 Macy's Thanksgiving Day Parade, a televised event with tens of millions of viewers.
Now you know. Go and rickroll some friends! Also, you shall become a newfag. Lowest creature ever. But you'll be on the right road in /b/coming someone.
