The clip comes from a live Caifanes performance in Texcoco, where the audience shouted for an encore at the end of the show. Chanting otra, meaning another one, is a long-standing tradition at concerts in Spanish-speaking countries, similar to shouting encore in English. Caifanes are one of Mexico's most influential rock bands, so recordings from their shows circulate widely among fans. Short crowd chants like this later spread online as reaction sounds, reused far from the original concert to celebrate performances, wins and funny endings.
