The line comes from the Russian dub of The Fast and the Furious: Tokyo Drift, released in 2006 as the third film in the Fast and Furious series. In the story the Mona Lisa nickname belongs to a Nissan Silvia drift car valued for its engine and condition, so the warning is about protecting the machine, not artwork. Russian speaking fans later lifted the short dub line from the film and reused it on soundboards and in edits as a standalone reaction for any cherished car, bike, gadget or collectible that someone might scratch.
