The Fullmetal Alchemist Handshake meme, featuring Major Alex Louis Armstrong and Sig Curtis, originates from the iconic anime series Fullmetal Alchemist. The scene depicts a moment of instant mutual respect between the two characters, characterized by their massive physiques and a sparkling, intense handshake. In internet culture, this template serves as the ultimate visual representation of two different parties finding common ground or a shared passion. It is widely used to highlight unexpected alliances or to mock how two disparate groups can be united by a single, often trivial, interest. The meme remains a staple for expressing 'manly' solidarity and consensus across various fandoms and social topics.
