Green FN is a slang term for "Green Fuck Nigga" that is particularly prominent on TikTok in the context of basketball clips. It is inspired by the NBA 2K video game series, where the quality of a player's basketball shot is measured by color, green being the highest quality. The term has been used ironically to comment on basketball players missing shots and sincerely to showcase a particularly stylish move, whether on the court or in another context. The slang term originated in early 2023 and spread again in early 2024 after it became a spam comment on TikTok.
