star docking 

To defecate into another's vagina.

Billy pressed his anus against Mary's open vagina. Billy cared a lot about Mary, so he wanted to make sure that the seal would be air-tight. Billy began pushing the feces out of his sphincter, while gently kissing the back of Mary's neck. Billy liked to imagine that his anus was a spaceship, and that Mary's vagina was also a spaceship, and that Billy's feces was passengers and cargo being transmitted from inside one spaceship to another. Mary liked to imagine the same thing. Mary cooed lovingly as Billy squeezed all of his feces into Mary's vagina. Billy was pretty sure that he was in love with Mary. Mary felt the same way about Billy. Billy and Mary could be observed star docking about 17 times a week on average.

Death Star docking station 

The act of taking a shit inside someone else's asshole.

I was hanging out with Eli one night when he asked me if he could shit in my ass. I told him I did not like Death Star docking stations.

There's nothing like a nice creamy Death Star docking station from your lover first thing in the morning.

Death Star docking 

(V) To place multiple penises inside the foreskin of another man's penis. The foreskinned recipient hums the Star Wars theme song while the penises enter to capture the feeling of spacecraft entering the mothership.

Frank and Jason were Death Star docking with Kevin last week at the sleepover

Andy ripped his foreskin in half while attempting Death Star docking with Jeff and Gary
