What is a Fatso slang?
Excuse me, could you clarify what you mean by "Fatso slang"? I'm not familiar with this particular term as it's not commonly used in the context of cryptocurrency or finance. Is this a slang term used in a specific community or culture? Or perhaps it's a misspelling or a reference to something outside of these fields? Could you provide some more context or background information to help me understand the term better?
