astronaughtyness

acts of sexual and other deviance precipitated by space travel; such activities generally are not sanctioned by NASA

Astrochick gets really high marks for peeing herself to avoid pitstops on her way to off the other woman;such singleminded focus is the sine qua non of astronaughtyness.

Astronauting 

When you stick your thumb up the ass and your middle finger up the vagina of a woman and toss her, off into a pool, down a bowling alley, or into the air in general. "Up, up and away!"

Astronauting was Joey's favorite activity until he lost his thumb in the war.
