Squidward Tentacles is the grumpy, artistic neighbour in SpongeBob SquarePants, the Nickelodeon animated series created by Stephen Hillenburg that premiered in 1999. Squidward dreams of being a celebrated clarinet player and artist, but his performances are usually pompous, out of tune and ignored by everyone around him. That contrast made his music a natural shorthand online for disappointment and self-pity. Clips of his theme spread through YouTube edits, TikTok videos and meme soundboards, where creators reuse it to mock a sad defeat. It remains popular because the character and the joke are instantly recognisable.
