“Perón, Perón, qué grande sos” is a famous line from the Marcha Peronista, the political march associated with Juan Domingo Perón and the Peronist movement in Argentina. Over time, the chant moved beyond rallies and became a familiar reference in TV clips, internet memes and social posts. It remains widely used because a second of the melody and wording is enough to evoke Peronism, party identity, nostalgia, irony or a joke about political fandom in Argentina.
