When someone takes something or someone away from you and you did not know whats the fuck is going on until the person ninja'ding you is laughing his/her/
ass off. The term ninja'd is usually
mixed up with
thiefed but the stupid sob that did that is spread across the atlantic ocean....Right now.
Tommy: Hey broski wheres my pencil....and my pants?
