No widely documented original source is attached to this clip in the details provided, so it is best understood as a soundboard favourite rather than a track from a known film, show or album. Its appeal is simple and reusable: the phrase party pooper is instantly understood, and the song format makes a gentle insult feel like a joke. On soundboards it sits alongside other short reaction tunes, ready to be played, shared and downloaded for edits where someone spoils the mood. That short length and clear premise keep it useful for quick social clips.
