Slippery ninja 

The sexual act of masturbating onto a floor, leaving a sticky or slippery mess (depending on floor surface). An action intended to cause discomfort and annoyance to a female partner in the hope that she treads in the newly applied man-porridge.

*guy applies slippery ninja technique, girl walks into room* *squelch*
Girl: Oh my god that's disgusting! Why would you do that on the floor?!
Guy: I am slippery ninja, and as an owner of ovaries, you are the victim of my mischievous ninja deeds!
