The best and coolest ninja. Usually the leader and in many cases good looking and smart. Has a strong influence on others and a very happy person. Athletic fast and most importantly green!

The untmost elite of newbies. The omninoob. Probably grew up really sheltered. One lacking in common sense or culture to the degree that he/she could be classified as being "skilled like ninja" at being a greenhorn. The proverbial 40-year-old virgin.
You don't know how to pump gas? You've never heard of Bruce Campbell? You've never played spin the bottle?? You're such a green ninja!

A better version of a ninja - it's green. Found in the forests of Africa. Considered a "n00b" for not being public enough.
