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.

Ninja Like

The act of logging onto a social networking site and rapidly liking a status/post before immediately leaving the website.

Not to be confused with Ninja-like

ninja handshake

A handshake involving many complex movements, but no one ever sees it because, as mentioned in the title, it is considered to be ninja-like, therefore cannot be seen.

Did you see their handshake?!

Of course not; it's a ninja handshake.

ninjagram

Someone with an Instagram account who posts no photos. Rather, they have the account so they can follow others, and stealthily stalk their posts, without contributing any of their own.

"I didn't know Steve had Instagram?"

"Yeah, but its totally a ninjagram account. He follows 100 or so people, but hasn't made a single post himself."

ninja ops

When you stealthily sneak-into your girlfriend's home after her kids have gone to sleep, so you can get some.

Man, I had to do some Ninja Ops at Michelle's house last night just so I could get some.
