To ninja poof would be to smoke (marijuana, tobacco, etc.) while hidden, usually very near people. Bushes work well.

When one wishes to execute the ninja poof, one must have a fart, or air buscuit, at the ready. When said fart is about come to fruition, reach one hand inside of your pants, cup your sphincter, let it rip, and then hold it. Once in your hand you will have about 5 seconds to throw it into someone's face
to self: I gotta fart (reaches in pants and farts into hand)
to friend: hey man you gotta come check this thing out in my hand (friend walks over; throws fart in friend's face)
To Friend: haha you just got ninja poofed

A Poof Ninja is another term for stupid looking female that jus woke up, and is extremely pissed off at the world. She has ninja abilities cause she is a karate master, and knows many major pressure points on the human body. The "poof" is for the marshmallow "poofness" her face looks like after having 3 hrs sleep cause of all the wild sex from the previous night.
Evan: Hey that chick sure looks like a poof ninja.

Ran: Hey poof ninja, wanna go get a facelift to fix ur face.

Arash: I love my poof ninja soooo much. vai

A 'poof ninja' is the most extremely radical creature in all the galaxy. It can poof from one place to another and sneak up behind you. This usually leads to slicing your throat open and screaming poof!
