The Boston Transfer is when one person takes a tube and inserts one end into his rectum and puts the other end into the rectum of another person. Once the tube is in place, one of the participants begins defecating into the tube to push the feces into the other participants rectum.
"I did a boston transfer with a girl last night. I guess I burnt her ass because she told me to stop eating spicy food."
