Eduard Van De Walle, known as Eddy Wally, was a flamboyant Belgian schlager singer who was a familiar television figure in Flanders for decades. A short television clip of him exclaiming wow in his distinctive, cheerful style began circulating online and was clipped, remixed and reused far beyond Belgium. As short reaction videos spread on social media, his single word became a universal shorthand for amazement that needed no translation. It remains popular because the delivery is sincere, distinctive and instantly recognisable even in a very short edit.
