Vak vak is the Turkish onomatopoeia for the sound a duck makes, the local equivalent of quack quack in English. Short duck quacks like this became staple soundboard clips because they are recognisable without any context or dialogue. The clip has spread in short animal videos, meme edits and reaction posts, where a half second quack can stand in for surprise, protest or simple silliness. Its brevity keeps it reusable across languages, since listeners understand the animal reference even if they have never heard the phrase vak vak before.
