What does it mean if someone tells you that are like a cake but cakes already been eaten?

That's a strange and possibly insulting phrase! Here's a breakdown of what it could mean:

* You're desirable but already taken: This is the most likely interpretation. The person is comparing you to a cake, which is delicious and tempting. However, the "already been eaten" part implies that you're in a relationship or unavailable in some way.

* You're not as exciting anymore: The speaker might be implying that you've lost your initial appeal or excitement. Like a cake that's been eaten, you're no longer "fresh" and appealing. This is a harsh and disrespectful way to describe someone.

* You've been through something difficult: This interpretation is less likely, but the phrase could be a metaphor for having experienced hardship. Just like a cake that's been eaten has lost its original form, the person may see you as having been changed by a difficult experience.

Important: Without more context, it's hard to say definitively what the person means. If someone says this to you, it's best to ask them to clarify what they meant. If their intention seems disrespectful or hurtful, it's okay to let them know that their words are not appropriate.
