HOW ARE YOU UN GREEK?

The phrase "How are you un-Greek?" doesn't have a standard meaning in English or Greek. It seems to be a playful or nonsensical construction. To understand what someone might mean, you'd need more context. Perhaps they're:

* Making a joke: They might be playfully implying something unexpected or contrary to typical Greek behavior or stereotypes.

* Using a neologism: They might have invented the phrase to express a specific idea.

* Misusing language: There might be a misunderstanding or error in their phrasing.

To get a clear answer, you'd need to ask them what they mean by the phrase.
