The time that a party really "begins", no matter what scheduled time the party was actually supposed to start previous. This is the time that, without fail, droves of people show up all at once and a party can go from almost non-existent to full-fledged rager.
"Man, this party was so lame for like the past 3 hours, now it's insane! (Looking down at watch, seeing it's around 11 PM) 11 O'Clock Rule, happens every time!"

Get the 11 O'Clock Rulemug. The ginger, and/or daywalker, equivalent of of the five o'clock shadow. Instead of darkening the skin like it's brown or black counterpart, the five o'clock flair in fact lightens the skin, or renders it reddish/orangish.
Male (to daywalking friend): You've got quite the five o'clock shadow going on.
Daywalker (to male friend): Don't you mean five o'clock flair?

Get the Five O'Clock Flairmug. Girl who is so thin she looks like the hands of a clock at 12:00. Wears size 00 jeans, A cup bra, prefers thongs because they treat her small, but round bottom just right.

Get the Miss Twelve O'Clockmug. The face you see on a person at work around three o'clock after the morning coffee has completely worn off. The expression illustrates extreme exhaustion with undertones of bewilderment and uncertainty.

Get the Three o'clock facemug. A normally shaved bush that's gone to sand-paper status, giving her "lady parts" a "five o'clock shadow" effect. Either 2 or more days unshaven in the vagina region.
Sandy wanted sleep with this man desperately but she hadn't shaved down there in days and thought that her five o'clock vagadow would turn him off forever.
