A den is a secret place where people meet, usually for a dishonest purpose. I could provide you with the addresses of at least three illegal drinking dens
a lair of wild beasts (Ps 10: 9; 104: 22; Job 37: 8); the hole of a venomous reptile (Isa 11: 8); a recess for secrecy "in dens and caves of the earth" (Heb 11: 38); a resort of thieves (Matt 21: 13; Mark 11: 17) Daniel was cast into "the den of lions" (Dan 6: 16, 17) Some recent discoveries among the ruins of Babylon have brought to light the fact that the practice of punishing offenders against the law by throwing them into a den of lions was common
If you describe a place as a den of a particular type of bad or illegal behaviour, you mean that a lot of that type of behaviour goes on there. the one-bedroomed flat that was to become his den of savage debauchery.
