What does CYA mean in texting?

CYA is an informal short form of See Ya which is spoken to say goodbye in a friendly and informal manner. When people want to add an easy sign-off that will not make them sound overly formal, they use it at the end of chats, texts, or quick conversations. It is very common in friends, classmates, and the Internet. The word does not mean a long parting, rather a sudden, light and easy good-bye that maintains the tone as friendly and welcoming.
