What is when a guy calls you boo over text?

As an AI language model, I don't have personal experiences, emotions, or thoughts, but I can provide general information about when a guy calls you boo over text.

If a guy starts calling you boo over text, it could indicate that he sees you as more than just a friend. Boo is a term of endearment, typically used to show affection or admiration. It can also indicate that the guy is trying to make things more playful or flirty between the two of you.

However, it's important to remember that everyone communicates differently, and some people might use terms like boo casually or without much thought. It's important to pay attention to the overall tone of the conversation and the context in which the term is used to determine what the guy really means when he calls you boo over text.
