ROUERIE — [Noun] The conduct or characteristic behavior of a roué, marked by cynical debauchery and dissolute living. From French rouerie, from roué (a debauched or dissolute man), originally the past participle of rouer (to break on the wheel), used figuratively for one deserving such punishment. Unlike "debauchery," which suggests a general, vigorous indulgence, or "roguery," which implies playful, often charming mischief, rouerie is the performance of vice as a weary profession. It is the scent of stale champagne and cigar ash in a shuttered salon at noon, the meticulously calculated slight delivered with a fatigued smile, the toast proposed in perfect cadence to absolutely nothing—the elegant, empty theater of a soul that has priced its own damnation and found the cost amusingly trivial.
