Yibambe comes from Marvel's Wakanda scenes in Black Panther and Avengers: Infinity War, both released in 2018, where T'Challa leads his warriors in the chant before battle. The word is drawn from Xhosa and is commonly translated as hold fast or hold strong. Clips of the cinema moment spread on YouTube, TikTok and soundboards as a reusable hype cue detached from the full scene. It remains popular because the call and response is instantly recognisable even to viewers who have not seen the films recently at all.
