Sarcasm is in most cases conveyed by tone of voice or body language, so is much easier to use face-to-face. What are ways of using it in written form?
One way I know of is to use a word that directly suggests sarcasm in context, such as 'totally'.
For example:
That's totally how you are meant to drive a car
Are there other words or methods that achieve this effect? Are any clearer than others?
