What is what does it mean when a guy says hey you?

As an AI language model, I don't have personal experience or feelings, but can provide general information on what the phrase "hey you" might mean when coming from a guy:

• It's a casual greeting: The guy might be acknowledging your presence and starting a conversation, especially if you're in the same physical location.
• He knows you but forgot your name: If the guy recognizes you but can't remember your name, "hey you" is a way of avoiding an awkward pause while trying to remember.
• He wants your attention: Depending on the context and tone, "hey you" might be a way of trying to get your attention and initiate interaction.
• He's flirting: If the guy is interested in you, "hey you" could be a way of testing the waters and starting a playful encounter.
• It's just a habit: Some people use "hey you" as a default greeting, similar to "hi" or "hello", without necessarily attaching any special meaning to it.
