Galo Sengen, also known as the 'Cockerel Declaration' or the 'DJ Wagner Rooster,' features a highly stylized, muscular rooster strutting with intense confidence to a rhythmic Brazilian track. The animation originated from a Japanese 'MAD' video on Nico Nico Douga, blending high-quality animation with the high-energy song 'Galo Sengen' by DJ Wagner. The meme gained global popularity due to the absurdity of a rooster possessing such overwhelming 'main character' energy. It is typically used to represent someone entering a situation with extreme unearned confidence, or to underscore a moment of triumph with its infectious, driving beat and fluid motion.
