look up any word, like tribbing:
Usually seen on boards such as 4chan where a person will post an image of something and leave 'I'm just going to leave this here' at the side as to start some kind of conversation regarding that said picture.

Said picture usually starts a lengthy debate and is usually a picture of quite random material.
