"Wubalubadubdub" first appearing on the adult cartoon-series "Rick and Morty" is the catchphrase of the main protagonist and mad scientist Rick Sanchez. In the tongue of Birdman's
people it means as much as: "I am in great pain, please help me."
Rick uses the phrase continuously throughout the entire series in a rather carefree, trivial manner. One could interpret that the 80-year old
genius lived through so much sh*t, the
depression and thoughts of the absurdity of existence, and nothing that throughout the years could quench his nihilistic tendencies lead to him himself accepting and embracing the reality he's witnessing by turning his own wish for deliverance into a catchy joke on himself.
Person A: "I heard your girlfriend dumped you, your
parents both died in a car
crash and you lost your job yesterday. That
suck man, want to talk?"
Person B: "Pf, whatever. Wubalubadubdub"
