Nom de Zeus comes from the French dub of Back to the Future, where it translates Doc Brown's English catchphrase Great Scott. The 1985 film made the eccentric inventor famous worldwide, and French audiences adopted his startled outburst as a playful substitute for a stronger oath. Clips of the line later circulated in French memes, reaction videos and edits, where its theatrical delivery made it easy to reuse out of context. It remains popular because it is short, instantly recognisable and carries both nostalgia and humour in just three words.
