Here are some examples of how "beffa" can be used:
* La beffa del destino: The mockery of fate.
* È stata una beffa per lui: It was a defeat for him.
* Ha subito una beffa: He suffered a humiliation.
It's worth noting that "beffa" has a more direct and harsh connotation than the English word "mockery". It implies a more pointed and deliberate act of humiliation.
