Here are a few possible interpretations:
* "You've run out of Spanish": This could be literal, meaning you've exhausted your knowledge or ability to speak Spanish.
* "You're done with Spanish": This implies you're giving up on learning or using Spanish.
* "You've had enough Spanish": This could suggest you're tired of hearing Spanish or that you're not interested in continuing a conversation in Spanish.
* "You're out of luck": This is more of a playful or sarcastic way to say you're not going to get what you want because it requires Spanish.
It's important to consider the tone of voice and the context of the situation to understand the precise meaning of "se te acabó el español."
