Karen (COVID-19 Slang)
A “Karen” is a popular mocking slang term as somebody tattletaling to the police or person of authority for witnessing a mass gathering of fun, healthy, and outgoing people who are violating social distancing procedures during the 2020 COVID-19 Pandemic. A typical Karen is ideally obnoxious, controlling, takes everything seriously, nagging, party-pooper, and the rain on your parade type of person.
I saw that the police was called in at a park to disperse a large group people. A Karen (COVID-19 Slang) must of snitched to the police and ruined their fun.
