The phrase is Greek in origin as a language, written in Latin letters as epese to moro moy, and it circulates online mainly as a short reaction sound rather than a longer recording. Its brevity and panicked tone have made it easy to reuse across edits, where creators rely on the shout itself rather than any known source scene. Because the meaning is understood even from the delivery alone, it travels beyond Greek speaking audiences as a universal sound for a sudden fall or dropped object.
