The 'We Don't Do That Here' meme features King T'Challa, portrayed by the late Chadwick Boseman, in a scene from the 2018 blockbuster Avengers: Infinity War. In the scene, Bruce Banner attempts to bow to T'Challa upon his arrival in Wakanda, to which T'Challa responds with the now-legendary line to indicate that such formalities are unnecessary in his country. The image quickly became a viral sensation as a humorous way to reject specific social behaviors, trends, or opinions. It is widely used across the internet to enforce unwritten rules or to playfully gatekeep communities from unwanted influences.
