When a man shits into a womans vagina.

The act of defecating directly into one's vagina. Like a space ship attempting to dock to a space station, "space docking" involves very accurate control and near-perfect alignment of the two orifices.

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.

When one man has a circumcised penis and the other man has an uncircumcised penis, the men go tip to tip and the uncircumcised man rolls the "hood" over the other man's head.

This is a variation of the standard practice for more experienced partners. It's where you freeze a shit so it becomes extremely solid and then proceed to use it as a dildo on the female partner.

to excrete inside a condom, freeze the condom and then use like a penis to give some one anal plessure.

This involves 2 people. One person takes a big long poop and wraps it in plastic wrap. Then you put it in the freezer. When frozen, take out and insert into the other's anus!
