"Nothing happens, and you?"
Here's a breakdown:
* "No pasa nah" combines "no pasa nada" (nothing happens) with "nah" (an informal English word meaning "no").
* "Y tu" is the Spanish equivalent of "and you".
This phrase is used in a casual, friendly way, often to ask someone how they are or what they are up to. It's a way of acknowledging the other person and engaging in a light conversation.
However, it's important to note that the phrase can be considered informal and slangy, so it might not be appropriate for all situations.
