A Real Life Big-Lipped Alligator Moment, Flashmobbing consists of coordinating a large number of people to show up in a given place at a given time, usually to do something silly and then disperse. Coordination is done primarily with some form of mobile messaging and relies on a Friending Network to amass crowd size.
Flashmobbing just for the sake of flashmobbing has become somewhat passé. It still finds some interesting applications in a real world-new media interaction games.
The phenomenon was anticipated in Larry Niven's 1972 short story, "Flash Crowd", in which the spontaneous formation of huge mobs at the site of interesting events was the inevitable consequence of cheap, readily-accessible teleportation. Really, all it took was cheap, readily-accessible communications. The idea has also been used as proof that backward time travel is impossible: if it was, there should be flashmobs at every major historical event.*
