And also misused quite frequently. Its origin was a white woman who called the police on a group of black people who were doing nothing wrong other than being black in the wrong place.
Now it's been abused and overused to where I don't even know what it means anymore. Lady comes outside to ask TikTokers to quit doing burnouts in her yard and it's 'shutup kawen, stupid kawen LOL amirite'
My daughter saw this in person, where a woman was mad at people at the butcher section of the grocery store, calling woman who bought a whole chicken an 'animal murderer'. Plot twist: the very same woman had chicken breasts and thighs in her cart, but because they were not a whole chicken, she disassociated them from the animal they came from. I rest my case.
Also, central park karen is a recent addition to the long history of using karen as a punchline, anytime you think you know the origin story, check know your meme first, you might be surprised: https://knowyourmeme.com/memes/karen
I don't think there's anything wrong with a little stereotyping: the only reason it's "bad" is that actual bigots ruin the fun, so to speak. If anything, I feel bad for people named Karen.
