"Florida man" is something of a running joke in the United States. It references the fact that often, you'll see a lot of very strange, silly, or disturbing news stories that take place in Florida. Often times the headline will begin with "Florida Man..." Followed by a ridiculous event. A few stories that come to mind are the time a man from Florida ate another man's face, or when a woman in Florida stabbed a pizza delivery guy for forgetting her garlic knots. Some people like to joke that the headlines are not about separate people in Florida, but rather one single person using a super hero allias- "Florida Man" as opposed to say, Batman or Spiderman.
