Karen

Word immature boys (of all ages) on the internet have repurposed from it's original meaning - an entitled white woman who treats service people like sh*t and calls the cops on black people for breathing - to any female who disagrees with them, especially if he is too stupid to refute her argument.

"Karen": "I just think you should be a little more careful with your words because it sounds like you are promoting domestic violence."
Little Boy of Unknown Age: "Shut up, Karen. Why don't you go call the manager."
