Orangutan Ganja - Really strong weed that Asian Orangutans smoked with Budda. Now used as a marketing term universal adjective that has largely lost its original meaning. Used to describe strong weed (i.e., OG Kush, OG Sativa, OG Indica, etc.).
Hey, I got some OG at the dispensary.
This stuff is real Orangutan Ganja.
Unlike the more commonly used unabbreviated term "Original Gangster", this alternate definition refers to "Original Gypsy" meaning anyone that exhibits prowess in the ways of the gypsy (slight of hand, sticky fingers, trickery, cunning, charming, etc.)
He is such an O.G. (original gypsy), he called comcast and convinced them he was switching to direct tv so they gave him 30 bucks off his bill each month plus 3 months of stars for free!
