Sardonic expressions are a form of communication that conveys a mocking or cynical attitude. They often involve irony, where the speaker says one thing but means another, typically to highlight the absurdity of a situation. This type of expression can be found in literature, film, and everyday conversation, often used to critique social norms or behaviors. These expressions can be delivered through tone, facial expressions, or specific word choices. Famous examples can be seen in the works of writers like Mark Twain or in characters from television shows like The Office. Sardonic humor can serve as a coping mechanism or a way to provoke thought.
