“Flash mob” is a term from 2003 to describe a sudden “mob” of people, such as for a public performance art project. “Flashmobbery” has been cited in print since 2006 and “flash mobbery” since at least 2008.
 
“Flash mobber” or “flahsmobbery” (flash mob + robbery) became a popular term in 2011, when many of the flash mobs were assembled to rob convenience stores.
   
 
Wikipedia: Flash mob
A flash mob (or flashmob) is a group of people who assemble suddenly in a public place, perform an unusual and seemingly pointless act for a brief time, then quickly disperse, often for the purposes of entertainment, satire, and artistic expression. Flash mobs are organized via telecommunications, social media, or viral emails.
 
The term, coined in 2003, is generally not applied to events and performances organized for the purposes of politics (such as protests), commercial advertisement, publicity stunts that involve public relation firms, or paid professionals. In these cases of a planned purpose for the social activity in question, the term smart mobs is often applied instead.
