Ninjah is the culture, and lifestyle, in ancient Eastern civilizations. It is different from Ninja Which is a kind of warrior. Ninjah uses the energy of all the life around it, and draws it to attack things, with Ninjah-Fu. 1 Ninjah per hour is so fast, it breaks the ligth, speed, and time barriers. Raptor Jesus and Chuck Norris can move at these speeds. Moving at 1Nph, it would only take 10 minutes to get to Mars.
Dude, she moved at Ninjah speed away from me when i told her i had AIDS.

Chuck Norris brings justice at the speed of Ninjah!
