SpongeBob SquarePants premiered on Nickelodeon in 1999, created by Stephen Hillenburg, and follows the optimistic sea sponge who lives in a pineapple in Bikini Bottom. The series became one of the longest running American animated shows and a constant source of memes, reaction images and short audio clips shared across social media. Sounds from the show spread because the voice acting and exaggerated expressions translate perfectly into brief, out of context jokes. Decades later, fans still use SpongeBob audio to signal silliness, nostalgia and lighthearted disbelief in everyday online conversations.
