OGs are experts in a certain field or niche that were there from the beginning and possibly even invented it. OG stands for Original Gangster. It originates from rapper @Ice-T’s track O.G. from the seminal album of the same name from 1991. Ice-T rapped about being a hardcore OG gangster from the streets and it now has come to describe anybody that has paid their dues in an industry, knows their sh#t and is not to be messed with.
Degen 2: “Girl, have some respect! Don’t you know that’s @Jon Bollinger? He’s the OG of technical analysis, almost invented it and created the @Bollinger Bands.”« Dictionary Menu
