The Hissu Amoto San (or Airmoto) meme stems from the niche Japanese subculture of MAD movies and Oto-MADs, particularly focusing on Masami Amoto, a figure associated with the Shinnyo-en organization. The term 'Hissu' (meaning desperate or frantic) describes the high-energy, often chaotic movements and chanting seen in the source footage, which was famously remixed with the soundtrack of the anime Air. Over time, the meme transcended its origins to become a staple of surreal internet humor, characterized by its fast-paced edits and the iconic Airmoto pose. It is primarily used to convey intense energy, frantic situations, or a sense of absurd spiritual enlightenment.
