A catchphrase that Morty's grandfather, Rick, uses in the Adult Swim animated comedy "Rick and Morty". Birdperson, a character who appears in the episodes "Ricksy Business" and "Get Schwifty" reveals that in his native tongue, it actually means "I am in great pain, please help me".
Bird Person: Morty, do you know what "wubba lubba dub dub" means?Morty: Oh, that's just Rick's stupid nonsense catchphrase.
