A silent-but-deadly fart normally released to assassinate unsuspecting bystanders in small cars, phone booths, and long elevator rides. These ninjas are known to have not only render average humans unconscious, but clear funeral homes, meeting space, classrooms, and other places where people would be caught with their guard down and nostrils open.
I almost died in at the office today when headed to the 47th floor in the elevator some jerk blew-ass released a ninja and everybody suffered from oxygen deprivation.

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.
