Used in two different ways, O.G meaning original gangster Or OG meaning original. The way you tell is the different context that it is used for example:

O.G = "Ye bro Tupac was a streight O.G(original gangster)."

OG = "I like how tupac didn't copy everyone else he was so OG(original).

OG

Stands for "Old Girl", usually used for a former female student of a highschool. Commonly used in old former british-african highschools.

I recognise that girl, she's an OG of this school.
