G-Check
When a gang member walks up to someone and demands their name, rank, set, and OG.
He walked up to me and said, 'State your name, rank, set, and OG, or I'll make you eat my shoe.'
She asked me who my OG was, and I said I didn't know, so she checked me.
He said he was from the South Side, so I checked him by making him tell me his OG.
