When a ninja is buzy doing a job. He is Ninjelic
The Ninja was 100% Ninjelic when his shadow was seen

On the job the Ninjas started all equily Ninjelic

A Ninjelic Ninja can run a mile faster than a ninja who dose nothing

He had to get Ninjelic when he was told who he was after

no one could see him while he was Ninjeclic

Any intentional action performed with grace, such as a stunt, trick or move, that is so sick, only a true ninja could execute.
Whoa dude, that back flip was so "Ninjelic"
