What does Woo mean in dating?

Excuse me, could you clarify what you mean by "Woo" in the context of dating? Is it a slang term or a specific action that one person might take to pursue romantic interest in another? I'm curious to understand how this term is commonly used and what it signifies in the world of dating. Is it a way of expressing affection, a strategy for attracting attention, or something else entirely? I'd appreciate it if you could elaborate further on this term and its significance in modern dating culture.
