I always thought of FAFO as a condensed proverb meaning basically "Think about what you're about to do and the potential consequences before you do it, otherwise you may overlook an obvious pitfall and blunder straight into it". I've mostly seen it applied to people behaving recklessly in one way or another. Sometimes it's rednecks doing some jackass style stunt with no payoff, sometimes it's a business making an obvious blunder that could have easily been avoided, sometimes it's a politician doing the same. In this sense it's less about some notion that doing stupid things will come back to hurt you in some unpredictable way and more about the self inflicted consequences that could have been avoided with like 5 minutes of thought. Like you could just leave that snake alone that you can clearly see and aren't being forced to approach, and you definitely don't need to put your hand in it's face and fuck with it, and oh shocked pikachu it bit you who could have seen this coming (except everyone). So to me at least, all it's saying is just think for a minute before you do something, and maybe don't do it if you're most likely going to regret it.

So to summarize

Fuck around = do something reckless without thinking

Find out = suffer the avoidable consequences of your lack of forethought
