When a man is fucking a girl either in the vagina, or in the anus, and tears through the skin separating the two. His penis is then in both of her orifices, and she is probably bleeding and screaming. Space docking can be accomplished either by entering the vagina, tearing through and exiting the anus. Or by entering the anus, tearing through, and exiting the vagina.

"When a space ship enters a dock, or dock "2" (The Butt (Taking a #2 refers to taking a dump; hence "dock 2")), but then re-docks into sector 1 (The Vagina), in result, leaving her with a high risk of getting a kidney infection or any other related venereal disease."

the once common, now lost art of pooping into a girl's vagina, space docking is enjoying a resurgence of popularity, particularly in the midwestern and northeastern United States (most notably Chicago and New York City) that reminds many art historians/scatologists of the beginning of the renaissance that began in Italy in the 15th Century.

The theory behind space docking stems from the act of excreting whilst weightless in space. Once free of the Earths gravitational field it is required that in order to poo without creating a terrible mess and upsetting your fellow astronauts a simple method of cellophane is used in order to capture the poo. This poo is then jettisoned into space...naturally at such low temperatures of deep space the poo in fact freezes. Space docking refers to excreting in cellophane, freezing the turd over night and then using it to provide anal pleasure to whomever requests to be space docked.
