Well, in this context, D stands for "Don't." It's a way to give a warning or a request. Like "Don't come near me, I'm committing arson." It's a way to show that you're not open to being approached or interacted with. But remember, it's always better to use more gentle and respectful language instead of threatening others. So instead of saying "Don't come near me," you could say "Please stay back, I'm not in a good mood right now."
