What is the slang egg?

Excuse me, I've heard the term 'egg' used in some cryptocurrency and finance circles, but I'm not quite sure what it means. Could you clarify for me? I'm interested in understanding the slang term and how it might be used in the context of crypto trading or financial discussions. Is it related to a specific type of asset, a trading strategy, or perhaps a term for a beginner in the field? Any insight you could provide would be greatly appreciated.
