the "OG Game" (bka, OGG!!!! MOFOCKER) is a game one plays out of boredom.
To play, one stays in a parked car for hours and everytime an oldie passes by one obtains a point. Bonus points for obvious oldie giveaways or sexual clothing
(eg. a cane, wet rained on clothing) are expected. points are only "YOURS" if you say you "claim" them
bryan: hey, let's play the og game!
patricia: "Oldee with a cane, 50 points"
bryan: "no, i claimed that first"
patricia: "damn, catch of the day"
brayn: "yeah, wet one, too"
patricia: "shit mang"
