Cotton Headed Ninny Muggins

1) A moron, idiot, dumbass, and overall stupid.

2) A human who accidentally got into santa's bag, and was raised by elves, who because of his human form, cannot make toys as fast as the elves and is inferior.

3) An inferior toy-maker.

Buddy: "Why don't you just say it? I'm the worst toy-maker in the world. I'm a Cotton Headed Ninny Muggins."
Elf: "No Buddy, you're not a Cotton Headed Ninny Muggins. We all just have different talents, that's all."

cotton headed ninny muggins

Somebody who feels like they can't do something right.

Buddy the elf thinks he is a cotton headed ninny muggins because he can only make 85 etcha sketcha's instead of 1000 like the other elves. He is NOT a cotton headed ninny muggins because he is a human as pappa elf tells him. A good example of a cotton headed ninny muggins is somebody that blows a country to pieces because they THOUGHT they had weapons of mass destruction. What you know somebody that did that? Wow then we all know a cotton headed ninny muggins!
