The 'Wow' meme features the late Belgian singer and entertainer Eddy Wally (Eduard Van De Walle) appearing from the side of the screen to deliver his signature catchphrase in a theatrical manner. While Wally was already a well-known kitsch icon in Flanders, he achieved global internet immortality in the mid-2010s when the clip was adopted by the MLG (Major League Gaming) montage community. It is typically used as a comedic punctuation mark for moments of surprise, impressive skill, or ironically underwhelming situations. The meme persists as a classic reaction clip due to Wally's unique delivery and the distinct visual aesthetic of the original video.
