karen

A person who gets upset and throws childish tantrums over small silly things that normal people would not even notice. They make threats, ask to speak to the manager, and call the police. Usually a woman but sometimes crybaby men exhibit karen behavior. Sometimes they get violent and assault the victim by hitting them with their hands, a hand held weapon, or even with their car. As a karen realizes they are not going to get their way, they get louder and more violent. Karens typically target people who are having fun enjoying life because they have no life and are jealous. Karens are among the most hated people in society and among the most laughed at.

My karen neighbors called the police because my dog wagged his tail at them and they reported that he tried to bite them.
A karen at the drive thru window held up the line because she claimed her soda did not have enough ice and wanted to make a complaint to the manager and have the worker fired.
