What does et tu spirit oh mean?

"Et tu, Brute?" is a famous Latin phrase, meaning "Even you, Brutus?" It's from Shakespeare's play *Julius Caesar*, where Caesar utters those words upon seeing his friend and close associate Brutus among the conspirators who have come to assassinate him.

The phrase "Et tu, Brute?" expresses extreme betrayal, shock, and dismay.

However, "et tu spirit oh" isn't a recognized phrase. It seems like you might have made a typo or misheard something.
