A contraction of the words "Ninja" and "Jaguar," a "Ninjaguar" is someone that is so ninja, that they possess not only the power of the Ninja, they also wield the power of a jungle cat that will tear you apart and eat you.
Dude killed fifty guys with nunchucks and swords and flamethrowers and shit! That mofo's some kind of Ninjaguar!
