Ay caramba is a Spanish exclamation expressing surprise, frustration or disbelief, long used before it became a cartoon catchphrase. It reached a global audience through Bart Simpson in The Simpsons, which premiered in 1989, where the rebellious schoolboy used it whenever he was caught or shocked. Online, the phrase evolved into short soundboard clips with stretched spellings like aai carambaa to show how long the shout is held. That exaggerated version now circulates in meme edits and reaction videos far beyond the original show.
