To treat guests with disrespect and inhospitality.
According to popular belief, rampant homosexuality in the cities of Sodom and Gomorrah incurred God's wrath and the subsequent destruction of the cities. However, according to some liberal scholars, whether homosexuality was the primary reason remains debatable. Arguing from Ezekiel 16:49-50 and Matthew 10:14-15, they assert that inhospitality played a significant role.
Since only Sodom has played a prominent etymological role for words depicting homosexuality, and Gomorrah has always played second fiddle despite the fact that its citizens are just as dead as the Sodomites, I would like to propose using Gomorrah to describe inhospitality. This will hopefully address the concerns raised by liberal theologians
Dude, are you trying to gomorrah me? Only one 6 pack in your fridge? That is so messed up, dude.
