A sex position where a dildo and a light switch is needed closed by. With the lights off proceed to have doggystyle sex with a woman and with a swift David Copperfield-esque motion, pull-out and stick the dildo in her so she thinks you are still in her. Then walk around to her front, switch on the lights, punch her in the face and yell, NINJA!!!
If The Ninja was done right, the mornings conversation should go like this:
Guy-"I totally Ninja'd you last night"
Girl-"You totally did"
Guy-"I totally Ninja'd you last night"
Girl-"You totally did"

A group (ninjas) or single person (ninja) that is trained in the martial arts. They are the coolest thing on the planet and live in competition with pirates.
Ninjas are so cool that I flipped out, kicked my mom in the face and crapped my pants all in one motion.
