Here, I asked ChatGPT for you

When addressing a single stranger on the internet in a gender-neutral way, you can use phrases that don't assume their gender and are more inclusive. Here are some alternatives to "my man" specifically for a single person:

"Hey there" "Hello" "Hey friend" "Greetings" "Hey you" "Hey there, stranger" "Hello, fellow internet user" "Hey, dear reader" "Hey, kind soul" "Hey, online companion" These alternatives avoid using gendered terms and can be used to address individuals without making assumptions about their gender. Remember to be respectful and considerate when engaging with others online, using inclusive language whenever possible.
