The time when you look at a clock and realize that a large portion of time disappeared. It is NEVER 'ninja o'clock', because by the time you've realized the time, it's at least a half-hour after you expected.
Friend 1: "Dude, what the hell happened to the day? I had that interview for that job."

Get the ninja-thirtymug. A female with the characteristics of a mythical unicorn meaning very rare of a find. And that of a ninja in the fact that if your not careful she will sneak up on you and get you to fall in love with her

Get the Unicorn ninjamug. A Ninja is someone who leaves a party or pub/club without telling their friends, all stealth-like (usually because they're tired or drunk and don't want to cop flak for leaving early). This practice can become a common prank between friends, sometimes blowing up into an all-out "Ninja War".
Friend 1: Where'd Beamers go?
Friend 2: Umm, she told me she was going to the bar for another drink. Wait... That was half an hour ago...
Friend 1: Unbelievable, she's done a Ninja again.
Friend 2: That's it, Ninja War declared.
