A term used to describe a resource EG. Pictures, Media, Quotes, etc, which has been found on a different website than other resources on it's page. In other words, a compilation of images where each image is from a different website is a compilation of internet floaters. On the other hand, if one were to compile images all from the same source, they would not be considered internet floaters.

Steve: They're internet floaters, I swear!
