The leadership of the nation has abandoned its duty, sinking instead into a life of moral corruption and endless self-indulgence. Rather than guiding or caring for the public, these individuals focus entirely on their own physical gratification, inviting one another to join in unrestrained drunkenness.
There are different perspectives on the exact identity of these corrupt figures. They may be false prophets who use the lure of food and drink to pull the people away from God, manipulating the masses into following their own twisted instructions [רד״ק]. Alternatively, they are complacent leaders who, after a long day of robbery and violence, sit down to comfortably enjoy the wealth they have stolen [אבן עזרא, ביאור שטיינזלץ]. Operating from a cynical and carefree worldview, they feast without a second thought, completely ignoring the suffering and loss of righteous people [מלבי״ם].
In their revelry, each person eagerly calls out to his friends, urging them to come and join the gathering [רש״י, מצודת דוד, ביאור שטיינזלץ]. Their deep lust is highlighted through repetitive expressions of desire [מצודת דוד]. They do not just pour regular wine for casual drinking; they specifically seek out heavily aged liquor designed to bring about profound intoxication and a total loss of the senses [מלבי״ם, מצודת ציון]. They drink until they reach a state of deep, gluttonous stupor [רד״ק, אבן עזרא, מצודת ציון].
This wild behavior is not a one-time event. Even as they drink, they confidently promise themselves that tomorrow will bring exactly the same indulgence as today [רש״י, אבן עזרא]. In fact, they go a step further, assuring one another that the next day's feast will be even greater. Driven by a constant desire to surpass their current excess, they guarantee that tomorrow's gathering will be far superior in both the sheer amount of alcohol and the level of physical pleasure [מצודת דוד, רד״ק, אבן עזרא, מצודת ציון].
