Ninja pic 

A photo taken of someone interesting, without the photographed knowing it and shared with friends. This is done by acting like you are trying to read something on your phone or taking a photo of a friend (accomplice) standing near them.

I snapped a Ninja pic of the lady with her skirt tucked into her tights and sent it to him.

Taking a photo in public with your cell phone without anyone knowing you just snapped it

My friend's wife was having a drink with another man so I moved closer and got a ninja pic to send him.

ninja pick 

A ninja pick is when someone tries to discretely pick their nose without anybody noticing.
Everyone notices though.

Sam: Stop ninja picking in the corner we can all see you!

Picture Ninja

A fat and/or ugly girl that disguises her bulk in nearly every picture she takes.

"I got screwed by a picture ninja I met through facebook for the first time today. Her picture was hot, but I never saw the 300 pounds her head was attached to."
