What Does Popup (PU) Mean in Text?

In texting and online chats, PU usually stands for “Pop Up.” People use it when they want someone to send them a message later, check in, or start a conversation when available.

It’s commonly used between friends and in informal conversations. Instead of writing a full sentence like “message me later,” someone might just say PU to keep things quick and simple.

Example:

 “pu when you’re free”

This means “message me when you’re free.”

In short: PU = Pop Up = Message me later.
