Uwu began as a text emoticon showing a cute, closed eye face, popular in anime fandom and kawaii online culture before people started saying it out loud. Voiced versions spread across Discord, Tumblr, TikTok and soundboards, where saying uwu became a shorthand for acting cute on purpose. The super uwu takes that idea further with an exaggerated delivery, and clips like this are now shared as quick reaction sounds, edit accents and ironic cute moments in gaming and anime communities.
