Cranial Rectal Inversion or HUTAS (Head up the ass syndrome), AKA AYRTFS? (Are you really that fucking stupid?) not to be confused with its cousin Faecal Encephalopathy, is chronic condition which causes the affected to be oblivious to everyone and everything around them or what I like to call a complete and udder asshole.

Those that suffer from Cranial Rectal Inversion usually have their heads so far up their ass they literally talk shit, are often such fucktards that they don't even know they are fucktards.

God, AKA Maynard James Keenen sumed up the definition of Cranial Rectal Inversion in his lyrical master piece The Pot when he said "Foot in mouth and head up asshole, what you talking bout? Difficult to dance round this one til you pull it out, boy."
