An upside-down question mark is a punctuation mark that is used to indicate a rhetorical question. It is typically used in writing to convey a sense of irony, sarcasm, or disbelief. The upside-down question mark is created by rotating a regular question mark 180 degrees.
The upside-down question mark is not a standard punctuation mark, but it is becoming increasingly common in informal writing. It is often used in online communication, such as in social media posts and text messages. The upside-down question mark can also be used in print media, such as in magazines and newspapers.
