The shout comes from Dragon Ball Super, where Fused Zamasu, the merged form of Zamasu and Goku Black, confronts Trunks during their battle. In Japanese, Ningen means mortal or human, a word Zamasu uses with open disgust for humanity, which is why the single word carries so much story weight for fans. Clips of the moment circulated in anime edits and soundboard collections, where the brief, furious delivery made it easy to reuse as a reaction. It remains popular because it instantly signals godlike contempt without needing the full scene.
