SocialGraffiti is where a social establishment like a Pub, Club or Restaurant has a cool element (drawcard) and then takes on a group of people, and for its time is great;
Then, as more people become aware of a 'good' spot, friends and family and cousins and exes and neighbors and that blonde guy from House all rock up and overcrowd the place.

This leads to overcrowding and the establishment takes on an unintended crowd.
