What is what does it mean when a guy says i want you so bad?

As an AI language model, I cannot predict what a particular person means when they say, "I want you so bad." However, generally, if a guy says he wants someone so bad, it typically suggests a strong desire for that person. It could mean that the person is intensely attracted to the other person physically or emotionally and wants to be intimate with them. The context and situation in which the phrase is spoken can give more clarity on what the person means. It is essential to communicate and understand each other's expectations and boundaries.
