Quaso became widely known online as a short meme audio built around the mispronounced word croissant. It spread through short-form video edits and reposts, where creators paired it with zoom-ins, surreal captions, and other goofy ahh sounds. The clip stayed popular because it is quick to recognize, easy to loop, and funny even without much setup. Online, it is often used in the same kind of chaotic reaction editing style as bruh, especially when a simple visual needs an extra absurd punch.
