The clip comes from Multimedios, a Mexican television network known for lively live programming, and it circulated online as a short soundboard audio titled Es Niñita. Its exact broadcast moment is not widely documented, but the phrase itself became a recognizable shorthand in Spanish-language meme culture for announcing that a baby is a girl. Creators reuse it because the delivery is instantly clear, even out of context, and it fits short-form videos, reaction edits and family announcements. Its brevity and upbeat tone have kept it in rotation long after its original broadcast.
