The origin of this specific recording is not documented, but the phrase itself comes from the French expression oh la la, used for surprise, trouble or amazement. Online, short named reaction clips like this one spread through soundboards and short video edits, where a recognisable voice and a loud delivery make them easy to reuse. The fort, meaning loud, in its name points to how users search for and share the stronger version. It remains used because the reaction is understood instantly, even without context or subtitles.
