Kwek is the written form of a duck quack in Dutch and Indonesian, similar to quack quack in English, and the double kwek kwek spelling is widely used in comics and childrens books. Short animal noises like this moved easily to soundboards and meme edits because they need no translation and are understood at once. The clip stays popular as a quick duck quack sound effect for cartoons, pet videos and reaction edits where a realistic farm recording would sound too serious.
