"Flash Crowd" is a 1973 English language novella by science fiction author Larry Niven, one of a series about the social consequence of inventing an instant, practically free transfer booth that could take one anywhere on Earth in milliseconds.
One consequence not foreseen by the builders of the system was that with the almost immediate reporting of newsworthy events, tens of thousands of people worldwide — along with criminals — would teleport to the scene of anything interesting, thus creating disorder and confusion. The plot centers around a television journalist who, after being fired for his inadvertent role in inciting a post-robbery riot in Los Angeles, seeks to independently investigate the teleportation system for the flaws in its design allowing for such spontaneous riots to occur. His investigation takes him to destinations and people around the world within the matter of less than 12 hours before he gets his chance to plead his case on television, and he encounters the wide-ranging effects of displacements upon aspects of human behavior such as settlement, crime, natural resources, agriculture, waste management and tourism.

In various other books, for example Ringworld, Niven suggests that easy transportation might be disruptive to traditional behavior and open the way for new forms of parties, spontaneous congregations, or shopping trips around the world. The central character in Ringworld, celebrating his birthday, teleports across time-zones to "lengthen" his birthday multiple times (particularly notable since the first edition had the error of the character heading the wrong direction, increasing that edition's value).
Niven's essay "Exercise in Speculation: The Theory and Practice of Teleportation" was published in the collection All the Myriad Ways In it he discusses the ideas that underlie his teleportation stories.

On the World Wide Web, a similar phenomenon can occur, when a web site catches the attention of a large number of people, and gets an unexpected and overloading surge of traffic. This usage was first coined by John Pettitt of Beyond.com in 1996. Multiple other terms for the phenomenon exist, often coming from the name of a particular prominent, high-traffic site whose normal base of viewers can constitute a flash crowd when directed to a less famous website. Notorious examples include the "Slashdot effect", the "Instalanche" (when a smaller site gets links by the popular blog Instapundit), or a website being "Farked" or Drudged (where the target site is crashed due to the large number of hits in a short time).
