The clip is credited to South Korean singer Yena, formerly of IZ*ONE, and her track Catch Catch, with the short baby call hook lifted for soundboard use. Fans began sharing the half-second vocal as a standalone reaction because it is instantly recognisable without needing the full song, and it spread through K-pop edits, short-form videos and meme compilations where a cute, teasing callout fits the moment. Its brevity keeps it useful for creators who want a quick idol vocal sting rather than a full chorus.
