When someone does something on Facebook just to make a point, or have everyone else see it. Can be done by a status, or joining of a group. Usually not a direct comment or wall post.
When someone new as joined facebook, and he/she does not have many friends, wallposts or photos. In most cases, this is a relativelyshort period of time, before the 'facebookling' grows out of control into a Self-Mutating-Facebook-Monstrosity.
