Wakanda Forever comes from Marvel's Black Panther, released in 2018, where it serves as the salute and rallying cry of the fictional African nation of Wakanda. Popularised by Chadwick Boseman's T'Challa and the film's cast, the crossed-arm gesture and chant quickly became a cultural shorthand for pride and solidarity. After the film's global success, the phrase spread through social media, fan edits and tributes, especially following Boseman's death in 2020. It remains widely used because it instantly conveys strength, unity and respect in just two words.
