Secret Ninjas 

It is a subtle way of indicating towards people of asian descent. They are secret ninjas.
Saying this means that they dont know you are calling them asians.

E: Hey bro, dont look now but there is a huge group of secret ninjas behind you

secret ninja society 

The acronym for SNS. there have been blogs and chat forums about weather they really exist or not. There websites say that there Ninjutsu is far to advanced than a normal ninjutsu dojo.I've bought there stuff and listend to there audio. What they were teaching were not advanced ninjutsu or banned ninja secrets as they have said in there website, it turns out it was only normal martial consepts which you would learn in an ordinary ninjutsu dojo. The stuff in the list that they said were baned weren't banned techniques.

Its up to you to believe weather the secret ninja society exists. but in my point of view the last ninja is Toshitsugu Takamatsu the grandmaster of Ninjutsu and the teacher of Masake Hatsume. He is the bloodline of the ninja in Segoku Era
