The remaining jizm or spunk that eminates, some time later, from ones japs eye after a wank. Even after a good shake and pipe clean.
After a morning wank before work, you clean up and head to work only to find when you go for a piss you have found a whole load of Ninja Jizz.

Cara: Oh, it's just the light.
Emily: Are you sure...?
Cara: Unless I'm being ninja jizzed, there is nothing there!
