Plyushkin (Плю́шкин) is a fictional character in Nikolai Gogol's novel Dead Souls. He is a landowner who obsessively collects and saves everything he finds, to the point that when he wants to celebrate a deal with the protagonist, he orders one of his serfs to find a cake that a visitor brought several years ago, scrape off the mold, and bring it to them. At the same time, his estate is incredibly inefficient; the cut wheat rots on the ground and any potential income is lost.
Today in Russia, the name "Plyushkin" is semi-humorously applied to people who collect and amass various useless things, a behavior known as compulsive hoarding. Sometimes the terms "Plyushkin symptom" or "Plyushkin syndrome" are used to describe such people (Cybulska E."Senile Squalor: Plyushkin's not Diogenes Syndrome". Psychiatric Bulletin.1998;22:319-320).
