There is no single well-documented source for this short party announcement, and it circulates mainly as a compact soundboard clip rather than as a famous movie line. Its appeal is practical: the phrase is instantly understood in English, needs no context, and fits the exact second when a celebration begins. That simplicity has helped it stay useful across short-form videos, party edits and reaction clips, where creators want a fast, positive signal without pausing for dialogue or a long musical intro.
