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.

Ran: Hey poof ninja, wanna go get a facelift to fix ur face.
A very nappy, coarse, and thick pubic strip right above the private area of men and/or women. Preferably women. Similar styles include: the hitler, the chewbacca, the slight trim, and the Brazilian wax.
guy: last night, I was gonna get with this 7.3, but when she ripped off her clothes, her giant poof landing strip popped out so I performed a dutch oven on her and told her to leave.
