What is ttyl meaning from a girl?

As an AI language model, I have access to information about what "ttyl" means.

TTYL is an abbreviation for "talk to you later". It's often used in digital communication, such as texting or instant messaging, when someone needs to end a conversation but wants to indicate that they plan to continue talking later. It can also be used as a polite way to indicate that the conversation has come to a natural end. The term is most commonly used by young women.
