Here are some possibilities of what the intended phrase could be:
* "Your tie's untied" - This is the most likely interpretation, meaning someone's tie is not fastened properly.
* "You're untied" - This could be a playful or metaphorical way of saying someone is free or not bound by anything.
* "You're untying" - This could indicate someone is in the process of loosening or removing a tie.
It's important to consider the context of the conversation to understand the intended meaning. If you can provide more information about the situation, I can give you a more specific answer.
