green fn

Green FN stands for a far more explicit phrase, "green f--kin' n---a" that's used to refer to someone who is particularly suave or cool. In its original use case, the term was fairly specific to the world of basketball. That's because the term originated from NBA 2K, a series of video games in which gamers get the chance to replicate an NBA season and play with or against the stars of the modern NBA. It is also used in a more slang way on tiktok, stating that you "rizzed" a person of the preferred gender.
