Top Definition
A group of people who just annoy the shit out of innocent people and sometimes "jump" them. These groups of people are usually found in the city, downtown, and public transportation. They are known for usually messing with skaters. Flash Mobbers have no relation to the other groups of people that appear from out of nowhere, to perform predetermined actions, designed to amuse and confuse surrounding people.
