"Karen" is a meme for women of boomer age who interfere with younger folk in ways that are pedantic and tone deaf. "Karen" is middle-aged and up, has short blond hair, and always wants to speak to the manager about the inconsequential infractions of the younger service workers. She has also been known to engage in racist police calls (although in reality those women have all had other names) and has merged with "Becky." Calling out that this meme is itself sexist and tone deaf will also get you called Karen.
Karen thinks she can order her burger "Medium Rare" at BK, just because their slogan is "have it your way"
