LANE: Oh my God, there’s a pool table.
RORY: And a deejay.
LANE: It’s like a teenage Sodom and Gomorrah.
Sodom and Gomorrah were two cities north of the Dead Sea mentioned in the Book of Genesis, and throughout the Old and New Testaments. They were destroyed by God in fire and brimstone as an act of divine judgement against them for their numerous sins, and have become synonymous with any decadent vice-ridden area which refuses to repent. It is possible that the story was inspired by a real-life earthquake in the area thousands of years ago, but that isn’t certain.
There is a general belief that the city’s main crime was homosexuality (hence the word sodomy), but it was a whole raft of sins, including cruelty, violence, blasphemy, stinginess, greed, idleness, pride, indifference to the poor, and any number of ill-defined sexual abominations. The Bible calls them lawless and depraved.
