The exact origin of arayyy is not clearly documented, so it is best understood as an internet reaction sound rather than a clip tied to a single show or film. Short vocal exclamations like this travel easily because they need no translation or context, and creators reuse them across short-form videos, memes and edits where a quick emotional reaction is needed. Its appeal lies in that simplicity: a single playful voice can signal surprise, teasing or delight, which is why it keeps appearing in new edits long after its first uses online.
