Ninja

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.

Someone sitting in the stall next to you whom you never hear until the toilet flushes, the sink goes off or just the bathroom door open and close.

Jim heard what I said about him in the bathroom; damn he must be a stall ninja!

Mox: Two words my friend: Ninja-Tweeting.
