Ninja Jizz 

When there is visible jizz on one's pants, yet the wearer of said pants has no idea how it came (no pun intended) to be there.

Emily: Nice white splotchy thing on your crotch...
Cara: Oh, it's just the light.
Emily: Are you sure...?
Cara: Unless I'm being ninja jizzed, there is nothing there!
