The phrase comes from Brazilian Portuguese internet slang, where vadia is used as a harsh, gendered insult, and this clipped delivery has circulated mainly as a short reaction sound rather than as part of a widely identified show, film or song. Because the line is short and instantly quotable, it has been reused in meme edits, reaction videos and messaging threads where a single dismissive judgement is funnier than an explanation. Its appeal lies in that cultural shorthand: listeners familiar with Brazilian meme humour recognise the tone immediately, even without knowing the original recording.
