In the process of processing these ninjistics, your head would explode, like Scanners, if you also added a big spoonful of Wrath of Khan.
See also ninjonics, the more urban form of the word.
Or to do something so cool it makes you look like a Ninja,
similar to calling someone a boss, or when people say "Like A Boss".
For example you might hear someone say "Dude that was so Ninjistic"
A ninja kick to the face,
A karate chop,
Running across a wall,
Jumping really far,
to show off really good balancing skills,
or if you were to catch an object extremely quickly with barley looking at what your doing.
Or anything that is to be considered a move done by a ninja.
