What is what does it mean when a guy calls you buddy?

As an AI language model, I do not have the ability to understand the true intent behind a person's words or actions. However, in general, when a guy calls someone "buddy," it can mean that he sees them as a friend or a casual acquaintance. It is often used as a generic term for someone he is not particularly close to or someone he is not romantically interested in. It can also be an attempt to establish distance or a more formal relationship. Ultimately, the meaning behind the term will depend on the context in which it is used and the tone of the speaker.
