Ninja Reacharound 

Unexpected joy from a nearly invisible source.

I didn't expect to enjoy that new Roland Emmerich film so much, but the experience was certainly a ninja reacharound.

Ninja Pole

A case often seen in shows like AFV and It Only Hurts When I Laugh, a ninja pole is a kind of pole of some sorts like a lamppost or street sign that you run into. You don't see it coming and you could've sworn it wasn't there, so when you walk along you ram into it and hilarity ensues.

I was walking down the street, minding my own business, then suddenly BAM! A fuckin' ninja pole got me!

Ninja Cat 

The end product of months of immense training, in the form of a kitten. In short, the ultimate weapon.

Ninja Cat Bob: It sure feels good to have butt secks.
Ninja Cat Henry: That's right.

ninja route 

quicker than the shortest way possible from point A to point B. Usually utilising unknown shortcut, back alleys or secret routes.

After arriving at their destination in record time, the rabbi says to the preist, "Damn thats the f#*kin ninja route and sh*t!"

Ninja shit 

When you wipe after you shit and the paper comes out clean... Like the shit was never there... mysterious and stealthy...

I love it when I take a ninja shit... I only have to wipe once!
