Dec. 31st, the day before Jan. 1st. On that night you are supposed to get drunker than you have the whole year, in order to usher it out for the next year of drinking.
The last night of the year in which noone really gives much of a shit about, but almost everyone uses the day as an excuse and tries to get totally wasted and/or laid.
new yaer's eve: when guys get drunk and forget how metrosexual they look...espicially when wearing glowing mouse ears.Ah the simple joy of new year's eve.
