A Jewish ninja skilled in the art of silently swiping pocket change from unsuspecting Japanese pachinko players. Often wearing a yarmulke and reeking of gefilte fish, quarterninjas are usually unsuccessful in their endeavors.
Hikaru: What the hell? I think a masked Jew just stole a quarter from me!

Ichiro: Yeah bro, you gotta watch out for those quarterninjas. They would steal a parking meter if it wasn't attached to the curb!
