flash mob (redirected from Flashmobs)

A phenomenon in which the organizer contacts a list of people by e-mail with instructions to gather at a public venue. The messages may be forwarded to friends, who forward to more people. At a predetermined time, they gather and perform some distraction such as waving their hands and yelling something at the top of their lungs for 30 seconds. Then, they quickly disperse before the police can arrive. Using cellphones, the flash mob can change its venue if the first one has been compromised for any reason. Why do people organize a flash mob? Because they can!
