o.g.
OG is short for original gangster, but now it's used by fake gangsters who think they're cool just because they know what OG means.
OG13: I used to be an OG. Now I'm just a guy who says OG all day.
OG14: You think you're an OG? You're just a studio gangster who bought a dictionary.
OG15: OG is a word that means nothing now. Just like my life.
