This clip circulates online as a short Portuguese meme sound, shared mainly for its exaggerated final vowel rather than for any particular event or celebrity moment. Without a clear single source, its popularity comes from how easily it can be reused: the September reference makes it seasonal, while the drawn-out eeeeee gives creators a ready-made reaction for excitement, impatience or playful hype. That combination has kept it useful year after year, especially when September approaches and people want a quick, recognisable audio cue to mark the change of month.
