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!

Shackteâu

A Shackteau is a humble, weather-beaten, structurally questionable shelter located in a spectacular or highly coveted place—Wales, Jackson Hole, Sun Valley, Crested Butte, coastal Maine, the Alps—where the building itself may be worth almost nothing, but the dirt, view, access, and mythology make it absurdly valuable.
In use:

Shackteâu - We thought it was an abandoned shed until the realtor called it a rare alpine Shackteâu with unobstructed views and listed it for $2 million.
