Morbid Obesity Of The Head = Beyond stupid, a new word for someone who displays a shocking, awe inspiring level of stupidity in any aspect of life, usually displayed online in some way.
Simple spelling mistakes especially in signage or placards being used in public, posts anywhere online which display the kind of stupidity that makes everyone else ashamed to be human, whether it be not wanting to have children now that the world has lost Michael Jackson, videoing yourself acting out said stupidity or taking a picture of yourself in a compromising position and allowing it to be archived online for the world to screw with, forever = Mooth

I think that covers it :P
