The term 'uwu' (also stylized as 'UwU') is an emoticon representing a cute, happy, or smug face, often associated with anime and furry fandoms. While its exact origins are debated, it gained widespread internet popularity in the early 2010s on platforms like Tumblr and DeviantArt. The 'u' characters represent closed eyes, while the 'w' represents a mouth, mimicking a 'cat-like' smile. Over time, it evolved from a simple emoticon into a full-blown internet subculture trope, frequently used to convey overwhelming cuteness or ironically as a playful reaction to something wholesome. It remains a staple of online communication, often paired with 'soft' aesthetics or used to mock overly sweet behavior.
