ninjarific 

adj.
1. Synonymous with terrific, but carrying extra weight due to the addition of the word ninja because ninja are supremely terrific already.

2. Terrific in a ninja kind of way.

3. Ninja + Terrific = Ninjarific

1. These cookies are ninjarific yo!
2. Your cosplay outfit is ninjarific!
3. That anime is super ninjarific!*

*Note: in this instance it can mean that the anime involved ninjas and was therefore terrific in it's ninjafulness.
