Irony punctuation

Irony punctuation is a way of showing that you are being sarcastic or not serious when you are saying something. It's called irony because the punctuation marks you use can make what you say seem different from what you actually mean. It usually involves using punctuation like question marks and exclamation points. For example, if someone said, "That was so nice of you!", without any punctuation, you might think they are being sincere. But if they said, "That was so nice of you!?" that changes the meaning - it seems sarcastic, as if they don't really mean it. So using irony punctuation changes the way your words are understood.
