Is OG the same as original?

Excuse me, could you please clarify something for me? I came across the term "OG" and I'm wondering if it's synonymous with the word "original"? I've noticed that it's used in various contexts, especially in the realm of fashion, music, and even cryptocurrency communities. Is there a specific context in which "OG" is definitively equivalent to "original," or is it more of a colloquialism that can be interpreted differently depending on the situation? I'd appreciate your insights.
