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!

schmegegge

Yiddish slang word meaning bullshit, baloney, hogwash, nonsense, crock of shit or hot air.

I don't buy the schmegegge about Morty sleeping with Moira.
His version of the story was pure schmegegge.
