Little is known about where Jon123456 first came from, and no clear source work, character or creator is attached to the upload. The name looks like a username plus numbers, suggesting it was shared on a soundboard under a personal tag rather than an official title. Clips like this spread through reposts, short edits and chat shares, where the lack of context becomes the appeal. It remains in use because it is flexible, filling reaction, transition and random humour slots without tying an edit to one specific film, show or viral moment.
