A rare and usually fatal disease of the teenage mind. Symptoms include a desire for kinky French sex with Saint-Just, irrational lust for Saint-Just, and the need to make shitty internet graphics of Robespierre and Saint-Just having gay sex.
Commonly occurs in teen girls, but is not limited to the female gender.
Random girl on deviantArt: OMG LIKE ROBESPIERRE AND SAINT-JUST BELONG TOGETHER. THEY ARE SUPER KAWAIII DESU!
Doctor: This is a classic example of Saint-Just-ness syndrome.
