from The Century Dictionary.

• noun A feast or festival; a noisy drinking-bout or revel.
• noun Synonyms Revel, Carousal, Wassail, Spree, Debauch, Saturnalia, Orgy agree in expressing times of excess in drinking; some of them include other sensual pleasures. They are in the order of strength and consequent reprobation implied. A revel is accompanied with some drunkenness, disorder, and noise. A carousal is by derivation a time of drinking deeply; it may be a bacchanalian feast, a noisy, unrestrained drinking-bout. Wassail is limited by its associations with the past so as to he chiefly poetic or to express deep drinking. Spree is considered a colloquial word, but seems likely to win recognition as a convenient word for a period of drunkenness which incites to wild and reckless action. Debauch is distinctively excess, having less reference now than formerly to eating, applying chiefly to gross lewdness or drunkenness, which is often prolonged. Saturnalia, like wassail, has historical associations; it is a strong word for license, noisy revelry, gross and continued debauchery. Orgy is by derivation a secret nocturnal debauch, and by usage a time of joining in a wild or frantic abandonment to drunkenness or lust, or both—the extreme in that kind of misconduct. See feast.
