A huge ninja, differentiated from an averaged-sized ninja (ranging in size from 5'3 to about 5'8) and the superior minja (5'3 and under). A hinja is generally 5'9 and above. It is by no means a hippe ninja, as suggested in the previous definition. We look down upon you, kind sir, in utter shame.
Dude, my hinja boyfriend is such a hinja. Even though I'm a minja. It's beautiful, really.
