Yes in the Aristocrats movie a comedy writer explains that space-docking is where you take a shit in a girl's pussy...however I believe there is a more accurate description...
"Okay, obviously there's a bit of confusion here, after reading the video and comments. "Docking" is when a man rolls his foreskin over another man's penis. Using a frozen shit (usually in a condom) as a dildo is an Alaskan Pipeline. Space-docking is when one person shits in to another person's ass and they pass the shit back and forth between each other, shitting it in to each others' asses. Kind of like Lady and the Tramp, but only with shit instead of spaghetti."
