ONIOMANIAC — [Noun] A person afflicted by oniomania, the compulsive, pathological urge to purchase goods. From oniomania, from Ancient Greek ὤνιος (ṓnios, "for sale") + μανία (manía, "madness, frenzy"). Unlike a spendthrift, who squanders with profligate glee, or a collector, who curates with connoisseurship, the oniomaniac is driven by the hollow mechanics of the transaction itself—the click, the swipe, the handing over of currency—as the only momentary salve for a chronic emptiness. It is the frantic click of a "buy now" button in the blue light of 3 a.m., the unopened packages accumulating like sedimentary layers of shame, and the exquisite terror of tracking a delivery van's progress across a digital map—a quiet archaeology of attempts to fill a void that merchandise was never meant to occupy.
