1.
the period from Thanksgiving through New Year's Eve, where anything you do has to be to the fullest and no rules apply. Eat, drink and be merry daily, and worry about your liver, your bulging waistline, and your job and other commitments in the remaining dark days of winter.

As an added bonus, living so excessively in this time period gives you the perfect New Year's resolution - just stop being so irresponsible!
Johnny: I went out until 3am Tuesday night, slept through two meetings, came to work at 2pm and left at 5pm for happy hour, where I ate the entire appetizer sampler platter for 4 by myself.

Chris: Aren't you worried about your job? Or your health?

Johnny: Month of excess!!
