Pi in the Sky 

When the passengers on a plane up in the sky are separately seated based on the the digits of the decimal number π—there are three empty seats between the first and second passenger, one empty seat between the second and third passenger, four empty seats between the third and fourth passenger, and so on.

On a Boeing 777, how many passengers could take part in the “pi in the sky” experience?

Big Guy in the Sky 

The phrase is used as a synonym for God.

When athletes thank God, they point to the sky.
I want to thank the big guy in the sky for all my success over the years.

Fire in the Sky

A sexual maneuver based on the terrifying alien abduction scene in the 1993 film of the same name. The act consists of throwing a handful of jizz into your partner’s mouth and then stretching your scrotum over their face. Search for the scene on YouTube for reference.

Claire told me she had an alien abduction sex fantasy so I gave her a fire in the sky and she was totally into it.
