Karen is a commonly known and used word among young people in english speaking countries(primarily the USA & Canada. The name Karen evokes thoughts of repeated entitlement among middle to upper aged women (although occasionally including people as young as early to mid 20s). Karen, as a term, a name and a lifestyle is known and used enough to warrant entire communities to spring up calling out one time freak outs and repeat offenses by these unwarrantedly rude and obnoxious members of society, the most well known of which being r/EntitledKarens on Reddit. Karens will also often play the victim card when called out, either claiming the person they were harassing was doing something to them or desperately seeking the approval of other Karens on facebook for their actions, hoping that the sheer amount of entitled screaming in response to said calling out will get the innocent fast food worker to either get fired or become obedient to what they want. This my friends, is the classic Karen.
