The phrase comes from Portuguese-language Dragon Ball Z, where Goku is the series' central hero, and já chega is a plain way of saying that something has gone far enough. This particular short recording was shared online among Portuguese-speaking fans as one of a set of funny clips, with the uploader crediting the YouTube channel Kesyn and Skelter as its source. Because the line is short, instantly recognisable, and easy to understand even without context, it has kept circulating in memes and edits where a quick, exasperated cutoff is more effective than a longer argument.
