The clip circulates on soundboards under the spelling perhèèèè, taken from the Italian word perché meaning why, with the ending stretched to suggest a long, drawn out cry. Its exact original source is not widely documented, so it spread mainly as a standalone reaction sound rather than as a quote tied to a known character. Short, language crossing frustration like this travels easily on meme pages and in edited videos, which is why the sound keeps resurfacing whenever creators need an exaggerated why.
