duckroll

Etymology
From. In 2006, implemented a wordfilter replacing  with  on, causing instances of  on the site to become duckroll. This inspired an anonymous 4chan user to create an image macro featuring a duck with wheels edited onto its body and the caption "duckroll." The image was later used to prank 4chan users, who were lured into clicking what was presented as an interesting link, but instead lead to the "duckroll."

Noun

 * 1)  A bait-and-switch Internet prank involving the sharing of a link that leads to a picture of a duck on wheels instead of what is claimed.
 * You told me that it was a really nice picture, but all I see is a duckroll.

Verb

 * 1)  To prank (someone) in this fashion.
