It should be noted that Macron's parents are both medical doctors, one a professor (i.e. highly educated), studied at one of France's top high school and then top university, and won a French literature national prize when in high school.<p>He's actually similar to Boris Johnson, who studied Classics at Oxford and likes to drop literary terms and quotations.<p>That being said "c'est pas bibi" et "fada", mentioned in the article, are slang (for the former) and dialectal (for the latter) terms that are ubiquitously known and certainly not 'upper class' or obscure, same for "poudre de perlimpimpin". "Pognon de dingue" is even vulgar, but something anyone could say in an informal setting. I would not call any of these "macronism".
