Karen

A Karen is a person who is very annoying and would like to speak to your manager.
She/He (there are male Karens) looks to Facebook for every piece of information and will scream at you if you say anything contradicting that. If you so happen to be selling a slightly overpriced item Karen will threaten to call the police on you and will scream. Karen also believes COVID-19 is caused by 5-G towers and thinks essential oils will cure it and is always an anti vaxxer. If somebody divorces a Karen, the Karen will take the kids. Is also very rascist

Bystander: Um, (lady/sir) that expired like 2 years ago.

KAREN: YOU ARE NOT THE BOSS OF ME!!!
Bystander 2: Such a Karen...
