The exact source of this clip is often less important than the phrase itself online. “In the beninging” spread as a short reaction sound and caption format across meme pages, repost accounts and video edits, where the mangled wording became the joke. It stays popular because the line is immediate, quotable and easy to drop at the start of a clip. It fits the same chaotic reaction-sound space as goofy ahh sounds, especially in fast meme compilations and ironic short-form edits.
