When someone gets wasted to the point that there brains are literally no longer in their skull, they are Kurt Cobrained.
"Ah, fuck! This kid on the sofa's Kurt Cobrained man!"
"His brains are all external to his skull and shit!"
"Ahhh! Fuck! Put a lamp shade over his head or something!"
"Ahhh! Okay, there we go. Now what?"
"Now we warm these Pot Noodles up."
