What does he flemixed you mean?

"Flemixed" is not a real word in the English language. It's likely a misspelling or a made-up word.

To understand what the person meant, we need more context. Can you please provide the full sentence or more information about the situation?

For example:

* Who said it? Knowing the speaker's background and the context of the conversation can be helpful.

* What was the topic of conversation? This can give us clues about the intended meaning.

Once I have more information, I can try to figure out what "flemixed" might mean.
