Sky-Dicking 

The practice of using an airplane to draw images of genatalia in the sky. Usually performed by military pilots because most male members of the military have an obsession with drawing images of genatalia (e.g., cock n’ balls) wherever they can.

Those F-18 pilots got in trouble for sky-dicking over Washington.

Sky Docking 

A lot like dry docking. After you completely empty the toilet of water commence with some good upper decker action. The lack of water makes it a lot like a dry dock. The fact that it is in the tank making it above the bowl gives it the term "Sky Docking"

My boss wouldn't give me a raised for the sencond time in a row, so i decided to give him unforgettable experience of a good sky docking. It took him forever to figure out where the brown water was coming from. Can you say ready-made gravy?
