The act of bumping your own thread/post/video etc. on a forum/website/image board/message board to make it more popular than it actually is among real people. Used as a way to 'kick start' a post to help it gain popularity.

It doesn't work, don't do it.
This post is boring, why is it this popular? Oh yeah someone must have been samefagging lol what a tool.
