A furniture store was closed and had to be opened by the manager to allow the "spontaneous" flashmob in. He saw the chance for free advertising and got it with TV news.

flash mob

Something that internet rookies think that people who use the internet do. Supposedly a "flash mob" is a bunch of random people who meet up to spontaneously do something ridiculous to confuse others.

These don't really exist. When they do, they are carefully organized, which makes them EVENTS... the kinds that people have been having for thousands of years.

Jeff: Ever seen one?

Jon: ...... OMG have you seen this video of a cat playing the keyboard?

Flash Mob

A term used by inner-city youth, usually in a gang and oftentimes African-American. Describes a quick, spontaneous shooting (hence 'flash') of an individual (or perhaps of a small group) by a gang of African-Americans (hence 'mob.')

The term 'flash mob' originated as some kind of strange gimmick where net-savvy nerds met in a public place to do something ridiculous, then quickly disperse.

However, 'flash mob' has gone from being something to laugh at to something to fear. Five or six blacks (or occasionally Mexicans, Asians or even white trash) with guns will jump a rival gang member, someone they have beef with, or even a random person, usually in a dark alley or parking lot, shout "flash mob!" and just open fire. A flash mob could also be a drive-by shooting where there are several shooters.
