Ninja Wank

the art of wanking quietly and discretely in public or in an area of high visablity, or simply the art of wanking like a ninja.
A secretive faction of monks from long and far have mastered this form of masturbation whilst going out there daily rituals.
It is said to bring inner peace and balance to ones self, but costs a fortune in laundry bills.

only the masterful eye can see someone having a ninja wank, but if someone does this would be the reaction...

man 1- 'Dude wtf is that man doing in his pocket?'

man 2- 'Must be having a ninja wank'

man 1- 'Holy shit i thought that was just in fairytales'
