A person needs to be at least 5% smarter than the task at hand in order to do it.

Also another word for dumbass.
Person walking down the street and trips over nothing. I look at my buddy next to me, "Ha, 5% rule".

Someone talking to you and they tell you that they failed at doing something, my response, 5% rule. ( means you dumbass)
