9/11

The 9/11 is a sexual activity in which a guy airplanes (sometimes called the superman in other cultures) a girl while the second guy dives in from behind. When they all three fall this is called the 9/11.

Last night Jack was airplaining Jill while I came in from behind. It was kind of unstable and I 9/11 'd it.
