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.
Guy1: Damn man, last night Suzy and I were fucking and she was laying on her stomach, and I was sitting on top of her facing away from her head, fucking her in the ass. And I fuckin pushed in hard, and next thing you know I pushed out of her fucking vagina!

Guy2: Either you have fucking Cheshire cat dick, or you space docked the shit out of her! Her pussy is gonna need some serious stitches. Sounds like your life is going to suck for a while. Have fun with your blue balls.

Guy1: Hey man. Whoa. Her pussy is busted. Not her mouth.

Where a subject poo's into a condom and freezes it. After about 24 hours or so it is taken from the freezer and the condom removed. Then with a little lube it is used as a sex impliment until the warm juices all melt together and the poo regains its normal runny state.

When two reluctant and kinky boys head to a remote area of a room to engage in rampantly and furiously placing the head of both of their flaccid and unused penises in a siamese conjoined adopted babies manner to have one male stretch his foreskin over the others to create a Jamestown ship to dock analogy. Both boys will giggle and be more excited than Tony the Tiger and erupt with massive loads of semen flavored cum.
While Ezekiel's dad goes to work, he invites his cuddly homo sapien-like boytoy Mario to come over and migrate to an open corner of the room to engage in Space Docking. Mario's excessive foreskin, due to the fact he was born with Crohn's disease and two Urethra's, is always used to create the boat in dock motion that makes Ezekiel keep coming back for more. Mario is also an illegal immigrant and an Auschwitz survivor.
