The exact original context for this clip is not documented, and its file metadata only points to a personal vlog recording, so it should not be attributed to a film, show or public figure. The German phrase itself is a common idiom for knowing the right way to do something, which helps explain why the short clip travels well as a standalone reaction. Online, it is mainly used in short-form edits where a clever solution, shortcut or life hack is shown, with the phrase acting as a compact, knowing comment on the trick just revealed.
