Rick Rolling is commonly thought of as linking a friend, who thinks they are getting something desirable, to a video of Rick Astley's "Never Gonna Give You Up", though this is not always the case. A Rick Roll may be amplified by having the window fly around your screen and, upon closure, release a stream of popups (usually displaying the lyrics) that will open as you close the previous, as seen at raygoldmodels.com. These can be humorous to witness over the shoulder, as well as to have an email response to.
Man, after I Rick Rolled my friend, he was super duper pissed off at me.
I like to close the popups as their respective lyrics end whenever I get Rick Rolled.
