However, it's often used in a more nuanced way, implying:
* You can't refuse: This is the most common interpretation, meaning that the person is making a request or demand that you can't decline.
* It's irresistible: It could be used to describe something so tempting or appealing that it's hard to resist.
* You have no choice: The situation might be such that you are forced to accept, even if you don't want to.
The exact meaning depends on the context. Can you provide more context? For example, who is saying this to whom, and what is the situation?
