PARIS -- A video of French President Emmanuel Macron admonishing a teenager who called him by a nickname went viral on social media Tuesday.

The video shows Macron shaking hands in a crowd, when the teenager -- using a diminutive for Macron's first name -- asks him: "How's it going, Manu?"

Macron stops and responds: "Call me 'Mr. President of the Republic,' or 'monsieur."'

He then adds: "The day you want to start a revolution, get a degree and learn to feed yourself, OK? You can start lecturing others then."

The exchange occurred Monday at a ceremony commemorating Charles De Gaulle's historic appeal for armed resistance against Nazi tyranny.

Macron tweeted a video of the discussion, prompting a flood of comments Tuesday. Some applauded the French leader's demand for respect, while others criticized what they saw as his arrogance.
