FlaSh-Lag Effect

-a visual illusion wherein a flash and a moving object that appear in the same location are perceived to be displaced from one another (MacKay, 1958; Nijhawan, 1994). Several explanations for this simple illusion have been explored in the neuroscience literature.

-The illusion has been tested in many aspects, through the game of baseball, and how flashes may affect the batter's perception of the ball.

- "FlaSh-Lag" was also the name of a relatively well known Console and PC Gamer from the years 1999-2004.
Chris Rock: Wow man did you just see how displaced that object was.

Jim Thome: Nah man, the flash just made you think it was displaced, that's called the Flash-Lag Effect

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.
