Those are not really examples of being RickRoll'd.
What you do is post a video with a title saying something like "Two Hot Babes Wrestling in Oil". However, in lieu of the subject matter, you submit the Rick Astley video. The person clicks on the link thinking they're going to see soft porn (or a car wreck, or a baby doing something cute) and BAM...you get Rick Astley.
You've been RickRoll'd.
That being said, I just DID happen to post a YouTube video of my girlfriend and her friends wrestling in oil:
Two Women Wrestling In Cooking Oil (Hot!)
