D'oh is Homer Simpson's signature exclamation from The Simpsons, the long-running animated sitcom that first aired in 1989 and made the frustrated grunt a global catchphrase. The Latin American Spanish version, where Homer is known as Homero, carries the same joke for Spanish-speaking audiences, and short clips of it have circulated for years on soundboards, meme pages and reaction videos. Like other Homer clips, it survives because the sound needs no translation to explain a mistake, a bad decision or a moment of instant regret.
