If this is the first time you're hearing the term "Karen" then I'm just going to go ahead and assume this is also the first time you've ever been on the internet, in which case I say welcome, and I hope you enjoy your stay.
But all sass aside, a "Karen" is typically a middle-aged woman who is angry, entitled, unbelievably rude, and possibly even racist to people in public, and who almost always appears in some sort of viral video or post highlighting just how terrible they truly are.
There are thousands of "Karen" stories out there for you to sift through in utter disbelief, but today's comes from a post that was submitted to the aptly named subreddit, r/IDontWorkHereLady.
