¡Ay, caramba! (pronounced [ˈai kaˈɾamba]), from the Spanish interjections ay (denoting surprise or pain) and caramba (a euphemism for carajo), is an exclamation used in Spanish to denote surprise (usually positive). The term caramba is also used in Portuguese. "¡Ay, caramba!" is used as a catchphrase of Bart Simpson from the animated sitcom The Simpsons.
The fictional character Bart Simpson from the animated sitcom The Simpsons (voiced by Nancy Cartwright) used the phrase "¡Ay, caramba!" (pronounced with an American accent) when surprised. It became one of his most notable catchphrases, further popularizing the phrase in modern pop culture. For example, in the episode "Selma's Choice", Bart, Lisa, and their Aunt Selma approach a very popular ride at Duff Gardens. Upon seeing the exceptionally long line for the ride, Bart exclaims, "¡Ay, caramba!".
