Usage

What does mob mean? A mob is an unruly and often violent group of people, especially one engaged in a riot or other lawless violence. Some mobs organize intentionally to engage in violence and destruction, but sometimes people assemble spontaneously and turn into a mob, such as in reaction to some event. Because people who have massed together in such a way typically don’t follow any formal leadership or string of command, mobs are known for getting out of control and engaging in chaotic, unpredictable, and often violent behavior. Sometimes, the word refers to a large group of people acting in an aggressive or hostile way in a virtual space, as in Don’t post that unless you want to feel the wrath of the social media mob. This sense of mob is often used as a modifier (adjective) to describe things carried out by mobs or involving mobs, as in mob violence and mob rule. Like the word riot, the word mob is sometimes intentionally used inaccurately to portray groups in a negative way when this characterization is not warranted. For example, an opponent of a protest might call a group of peaceful protesters a mob as an attempt to discredit the protesters and their message. The word mob can also be used as a verb meaning to assemble in large numbers or crowd around someone or something, especially in an unruly way, as in Holiday shoppers mobbed the store as soon as it opened or The star is mobbed by photographers every time she leaves her house. A place or person who has been crowded in this way can be described with the adjective mobbed. As a verb, mob can also mean to attack as a mob, as in Wave after wave of rebels mobbed the embassy. Mob is sometimes used as a noun in a more figurative way to collectively refer to common people or the masses, in which case it is typically preceded by the, as in His campaign platform is too subtle to win over the mob. This sense of the word often implies that the common people lack sophistication, intelligence, or are otherwise base and crude. This is what’s implied in the phrase mob mentality, which refers to a mindset motivated by the basest human instincts. Much more specifically, organized crime groups known as the Mafia are sometimes also referred to as the Mob. A member of the Mob can be called a mobster. Example: Perhaps the most distinguishing feature of a mob is that the group and the people in it have passed the point of being able to be reasoned with.

Etymology

Origin of mob¹

First recorded in 1680–90; short for Latin mōbile vulgus “the movable (i.e., changeable, inconstant) common people”

Origin of mob²

First recorded in 1980–85; coined by British video game developer Richard Bartle; shortening of mobile (in the sense “a moving sculpture hung from the ceiling”)

Explanation

A mob is a big, rowdy group of people. You might avoid shopping at the mall right before Christmas because you can't stand the mob of shoppers. A mob might gather around the piñata at a big birthday party or cluster in front of a music venue when tickets go on sale for a hugely popular concert. When people join one of these groups, you can also say that they mob, and "the mob" also sometimes refers to organized crime. You might describe the hundreds of people thronging the county fair on Friday night as a "mob scene." The Latin root, mobile vulgus, means "fickle common people."
