About this sound
A Portuguese voice clip saying 90 por cento dos casos, meaning 90 percent of cases. Creators use it as a dry reaction when a predictable outcome happens.
The sound is a Portuguese voice clip built around the phrase 90 por cento dos casos, which translates as 90 percent of cases. It is spoken plainly, with no music or effects behind it, so the words themselves carry the joke. The line works because it sounds like the start of a serious statistic, then leaves the listener to fill in the obvious ending. In a video it lands as a deadpan comment on something that happens repeatedly, turning a familiar pattern into a punchline. Its plain delivery makes it easy to drop over a reaction shot, a fail, or a moment when everyone already knows what will happen next.
