When you slpooge in someones face and they get it in their eye and it burns and gets an off white yellowish necklace and you don't know who did it.
I just got boomed by that Ninja Pumpkining.
Did you get a pearl necklace?
No, well its more of an off white yellow, did you see who did it?
you don't know who did it? well it wasn;t me or I'd have laughed about it.

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: Unbelievable, she's done a Ninja again.
Friend 2: That's it, Ninja War declared.
