Uwuh comes from uwu, the text emoticon used online since the early 2000s to show cuteness, happiness or smug affection, spoken aloud as part of anime and fandom slang. Adding the h and the :3 face gives it a softer, more drawn out delivery that spread through soundboards, Discord servers and short form edits. Creators keep using it because the meaning is instant without any context, making it a shorthand for kawaii reactions, ironic cuteness and playful teasing between friends in meme culture.
