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 wash

The act of cleaning, drying and putting away something so quickly in succession, it appears to the onlookers as if you never even used the utensil at all, thus having the speed of a ninja, or chuck norris.

Chad: Yo Pete did you get any food?
Pete: Yeah! I finished already.
Chad: Then wheres your plate? I don't see it in front of you
Pete: Dan just took it.
Chad: I just checked the kitchen there's no dirty plates...
Pete: He must've done a ninja wash.

Ninja Mission

When you do something you know you're not supposed to do (whether it's good or not so good) or when you do something that other people (like your parents) don't want you to do.

Well...sneaking out to Caid's party at 11 p.m. was a real ninja mission.

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.
