The clip builds on uwu, a text emoticon used in anime and fandom spaces to show a cute, pleased or shy face with closed eyes. Online, fans began voicing uwu out loud and repeating it for comic effect, similar to other kawaii catchphrases like nico nico nii. The triple uwuwu pattern spread through short videos, edits and soundboards because it is instantly recognisable, easy to loop and flexible enough to signal love, embarrassment or ironic cuteness without any dialogue or context needed.
