This noun denotes reckless, wasteful living characterized by excess and moral looseness. Paul warns believers not to get drunk with wine, which leads to 'debauchery,' but be filled with the Spirit (Eph 5:18). Titus must appoint elders whose children are believers, not accused of 'wild living' (Titus 1:6). Peter describes Gentiles as surprised when believers no longer join them in 'the same flood of debauchery' (1 Pet 4:4). The word combines wastefulness with moral dissolution, depicting life without restraint or direction.
