Here are some examples of how it might be used:
* "Caramba! ¡Qué sorpresa!" (Oh my goodness! What a surprise!)
* "Caramba, se me olvidó la llave." (Darn it, I forgot my key.)
* "Caramba, ¡qué calor!" (Good heavens, it's hot!)
It's important to note that "Caramba" is a somewhat informal expression, and it's not always appropriate in formal settings.
