What does GBY mean in slang?

Excuse me, I've been hearing this term "GBY" quite frequently in recent conversations within the cryptocurrency community. Could you please elaborate on what it stands for in slang? I'm quite curious as to its origin and significance within our field. Is it a shorthand for a popular strategy, a reference to a particular cryptocurrency, or perhaps a catchphrase used among traders? Any insight you could provide would be greatly appreciated.
