Começou is Portuguese for it has started, and this elongated version became a shareable reaction clip because the stretched final vowel makes the meaning instantly clear even to non-Portuguese speakers. It circulates on soundboards and in Brazilian meme and WhatsApp audio collections, where short shouted phrases are reused as punctuation for everyday moments. Editors keep returning to it because it works without context, works over gameplay or chat footage, and turns ordinary beginnings like a match loading or a friend arriving into a joke about anticipation finally paying off.
