What does Being Rick Rolled mean?

Question

I've always wondered that.

Answer 1

When someone describes something as interesting, then when you check it out, it's the rick roll song.

Answer 2

It's when you follow a seemingly normal link on a webpage and are redirected to the YouTube video for Rick Astley's "Never Gonna Give You Up".

Answer 3

An internet web prank where it would not close

The name Rick refers to 80's pop singer Rick Astley. The standard rickroll generally involves someone posting a link claiming it leads to something quite interesting (e.g. hot chicks in panties), but actually linking to a video of Mr. Astley singing "Never Gonna Give You Up." This is usually considered a major let-down.
