Seiya is the Pegasus knight at the center of Saint Seiya, Masami Kurumada's manga and anime franchise also known as Knights of the Zodiac, which began in the 1980s and built a huge following in Brazil. Portuguese dubs and fan edits turned dramatic battle lines into shareable jokes, and this clip condenses that style into one curse aimed at the hero. The added word encosto gives it a local, teasing flavor separate from a straight translation. Short anime shouts like this survive on soundboards because they work without context as instant overreactions.
