What does que buena tu ta mean?

"Que buena tu ta" is not a grammatically correct phrase in Spanish. It seems to be a combination of Spanish and possibly another language, likely with some misspellings.

Here's a breakdown:

* Que buena: This means "How good" or "What a good..." in Spanish.

* Tu: This means "your" in Spanish.

* Ta: This is not a standard Spanish word. It might be a slang term or a misspelling of another word.

It's impossible to give a precise translation without more context. Here are some possibilities depending on what the speaker intended:

* "How good your..." + something else: The speaker might be trying to compliment something about the listener, but they didn't finish the sentence.

* Slang expression: The "ta" might be a shortened form of a slang word.

* Misspelling: The speaker may have misspelled a different Spanish word.

To get a clearer understanding, you'll need more information about the context and who said it.
