The exact source of this version is unclear, but it is used online as a distorted Harry Potter joke clip rather than a clean soundtrack or dialogue sample. Sounds like this usually spread through reposted meme edits, short-form videos and soundboard uploads, where exaggerated volume and clipping become part of the humor. It stays popular because the reference is widely recognizable and the blown-out mix creates an instant shock effect, similar to how creators use a sad trombone for a deliberately overdone comedic fail.
