A Karen is a stupid, bossy, entitled woman (of any race, but most often seen as Caucasian) who demands things that she is not entitled to get and does things like demand to speak to your manager in a place you don’t work at, knowing you don’t work there, to get what she wants.

“Florida Man” is a lot easier. Basically, it’s a stereotype based on the huge number of news articles that are titled “Florida Man” followed by “does (insert name of truly colossally stupid activity here)”

Wow! When you want to explain something, you go all out. Thank you for taking the time and trouble. I understand both very well now.
Karen’s wear short skirts and long jackets and drive Chrysler Lebarons.
