The phrase is Brazilian Portuguese for wow guys, a legendary one, and the clip circulates as a reaction sound on Brazilian meme pages, gaming videos and short form edits. Its exact original recording is not widely documented, so it spread mainly through reposts, soundboards and downloads rather than a single credited show or film. The drawn out shout became shorthand for treating any rare drop or surprise appearance as a major event, which keeps it useful long after the first posts that popularised it online.
