Who is the Woo Woo man?

Excuse me, could you perhaps clarify who the so-called 'Woo WOO man' is? I've heard the term mentioned in the cryptocurrency and finance circles, but I'm not entirely sure of the context or the individual's significance. Is he a prominent figure in the industry, or perhaps a nickname for someone known for their eccentric or unconventional approach to investing? Any insight you could provide would be greatly appreciated.
