The phrase itself is a common colloquial Italian insult, roughly telling someone to go away in the crudest possible terms, and the doubled vai at the end adds a dismissive, go on, get lost emphasis. As a short soundboard clip it circulates as a reaction audio in meme edits, gaming chats and messaging threads, where its brevity makes it easy to drop in without context. It stays popular because the anger is clearly theatrical rather than threatening, so the clip works as comic exasperation across languages, especially in Italian speaking communities online.
