Ay carumba is a spelling variant of ay caramba, a Spanish exclamation Bart Simpson helped popularise as one of his best known catchphrases on The Simpsons. Voiced by Nancy Cartwright, Bart used the line throughout the long running animated sitcom whenever he was startled, impressed or in trouble. As Simpsons clips and reaction sounds spread across forums, video edits and soundboards, the short exclamation became a standalone shorthand for cartoon shock. Its brevity and unmistakable voice keep it in circulation decades after the show first made the phrase familiar to worldwide audiences.
