gabajabafala
A stupid made-up word that Robin Williams said a lot at NMH, like a brain-dead parrot repeating the same nonsense over and over.
'Gabajabafala! Gabajabafala!' he screamed like he was on a sugar high and had no idea what day it was.
During lunch, he said 'gabajabafala' so many times, the cafeteria lady gave him a free soda and a warning.
He tried to explain 'gabajabafala' to a kid, and the kid just walked away and cried.
