What is woo slang for?

Hey there, could you help me out with a bit of crypto jargon? I've come across the term 'woo' a few times in various crypto-related discussions, but I'm not quite sure what it stands for. Is it some kind of slang or shorthand that's popular in the crypto community? Could you please shed some light on this for me? I'd really appreciate it if you could provide a clear and concise explanation of what 'woo' means in this context.
