The line is tied to NouCome, a Japanese anime comedy built around absurd choices and school romance, where affectionate, over-the-top dialogue is part of the humour. Online, the short phrase has travelled far beyond any single scene, shared on soundboards and in short-form edits as a quick shorthand for cute, clingy, or teasing affection. Its appeal is similar to the repeated onii-chan, onii-chan chant, but the addition of daisuki makes the feeling explicit. That clarity keeps it useful for memes that need an instantly readable anime reaction.
