Patrick Star is the dim witted starfish best friend of SpongeBob SquarePants, the Nickelodeon cartoon that began in 1999 and was voiced by Bill Fagerbakke. Short clips of Patrick acting clueless became a staple reaction format online, captioned as Patrick be like for moments of empty headed behaviour. This particular tongue wobbling noise was lifted by fans into soundboards and short edits, where it spread as shorthand for derpy humour. It remains popular because Patrick is instantly recognisable and his silliness needs no context.
