Nom and uwu both come from internet anime and fandom slang rather than a single named series. Nom imitates happy eating, popularised in early meme culture, while uwu is a text emoticon for a cute, blushing face that fans began voicing aloud in the late 2010s. Short voiced versions spread through TikTok, Discord soundboards and anime edits alongside clips like tuturu and yamate kudesai. This 2-second take became a reusable reaction for feeding scenes, chibi characters and VTuber moments, kept alive because it reads instantly even without any visual context at all.
