Romans 13.13 says: Let us live decently as in the daytime, not in carousing and drunkenness, not in sexual immorality and sensuality, not in discord and jealousy.” It is obvious what drunkenness is, but what is “carousing”? The Greek word is “κωμοις”, “komos.” Strong’s Concordance defines this as:
a revel, carousal 1a) a nocturnal and riotous procession of half drunken and frolicsome fellows who after supper parade through the streets with torches and music in honour of Bacchus or some other deity, and sing and play before houses of male and female friends; hence used generally of feasts and drinking parties that are protracted till late at night and indulge in revelry.
This page elaborates on the Greek god Komos or Comus:
KOMOS (or Comus) was the god of revelry, merrymaking and festivity. He was the son and the cup-bearer of the god Dionysos…
It quotes Philostratus the Elder, from Imagines 1. 2:
And what else is there of the revel? Well, what but the revellers? Do you not hear the castanets and the flute’s shrill note and the disorderly singing? The torches give a faint light, enough for the revellers to see what is close in front of them, but not enough for us to see them. Peals of laughter rise, and women rush along with men, wearing men’s sandals and garments girt in strange fashion; for the revel permits women to masquerade as men, and men to put on women’s garb and to ape the walk of women. Their crowns are no longer fresh but, crushed down on the head on account of the wild running of the dancers, they have lost their joyous look; for the free spirit of the flowers deprecates the touch of the hand as causing them to wither before their time. The painting also represents in a way the din which the revel most requires; the right hand with bent fingers strikes the hollowed palm of the left hand, in order that the hands beaten like cymbals may resound in unison.
This gives me a better idea of what St. Paul had in mind.
