An OG is someone who's been around long enough to know a few things about the matters of life.
A teenager says "You don't know what i'm talking about. The matured adult says "I know all about it, I'm an OG."

2. In music lingo, OG means, an Original Version of a song that was recorded. Ergo, based on the the Master version. Often times confused with an OG Vibe track.
