Jordan The Ninja 

Dastardly handsome, very talented individual who takes on tons more than meets the eye. A person who is very skilled at a great many things which most abilities are unknown. Although the skill level is very high, this often blinds the individual to certain cues. Deep down, there is a longing to be known for who he truly is. A silent scream to be heard as a person.

At first I didn’t buy into Jordan The Ninja being a real ninja. But alas, I have discovered that you can never really know him unless you know him not. He really is Jordan The Ninja

on the ninja 

To get away with something with such stealth and skill that it can only be compared to that of a ninja.

Derived from the term 'on the sly' - To be on the sly, the active of sly. You can do something on the sly, maybe stealing something funny and legendary, like mine and Jimbo's road bollard. You could also have 'slying it'

First guy:
"Hey dude, I looked in the fridge just then and I cant find that steak that I had ready for dinner, Do you know where it went?"

Second guy:
"Not too sure bro, Sam was looking in there before. Maybe he took it on the ninja when no one was looking".
