Because its source is not documented, Tudo Começou is known mainly through its use as a shared soundboard clip rather than from a confirmed film or show. The Portuguese phrase is instantly understood by Brazilian viewers as the start of a long explanation, so creators reuse the short three-second line whenever a video needs instant backstory. It circulates in edits, group chats and short-form videos, where the unfinished sentence signals that a confession, a flashback or a funny disaster story is about to begin.
