So, a colleague of mine uses this term way too much but i really don't know whether he's using it in the right context. An example:
"So, i have 3 cars in the garage and they take up way too much space. Should i sell one off?...... Never mind that rhetorical question, i was just showing off."
...What? Isn't rhetoric supposed to mean something meant to persuade the audience?
According to my deduction, he uses it while asking a question that need not be answered. so what IS the correct meaning of the word?
