legend has it this name was once a nickname for a great man but now many people have forgotten what it stands for.
But itelligence tells me a "mufo" can be:
Any male that is always right, funny and is often mistaken for a god. This things are also there only downside. Often pet named as:
"Wow! He is one of those Mufo's"
"GOD! Why are you always right!"
"yes i am, and because i'm a mufo"
