ninja master

person worthy of leading a team of true ninjas (people that quietly and skillfully gets things done without drama).

Brian's a superstar at this company because he is a ninja master, and you have to be able to walk through walls to be a part of his team.

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.
