Ninja

Someone who has the ability to mindfuck others. Someone who is stealth enough to complete missions with other ninjas that involve high risk situations. A ninja can usually "ninja" information out of other individuals who are clear 'un-ninjas'.

Ninjas are usually dressed casually, and people don't usually peg these people as actual ninjas, but rather, ordinary and normal girls. Watch out though, there couldbe a ninja at your workplace.

And she could ninja the shit out of you.

co-worker: blah blah blah blah blah

ninja: (in her mind) - good to know I just ninja'd the shit outta you bud. I'm going to go tell my other ninja this classified information.

ninja spider

A spider so clever in its hiding ability it is never seen, preferring to live its life in the shadows.

I kill every spider I see, now only the ninja spiders remain.

Ninja whinger

Someone that complains by stealth in order to undermine their victims.
A person that uses something you've told them in confidence to get at you behind your back.
Someone that deliberately puts shit on you for personal gain.

Heads up man, that mofo is a ninja whinger - don't tell him shit.

ninja beat

The act of silently masturbating while in the same bed as your significant other, likely while they are asleep.

My girl didn't want to give me head during her period week, so I had to pull off the ninja beat several times.
