space-cuddling 

Cuddling in a zero-gravity or low-gravity environment so nobody's arm falls asleep.

-"Honey, could you get up for a second, my arm is asleep."

-"Fine. You know on the Moon colony this isn't a problem, it's nothing but space-cuddling, Tang, and golf."

-"Would you just let it go? We're not moving to Gingrich's lunar Jonestown."

See You Space Cowboy... 

At the end of a Cowboy Bebop episode, there is a black screen, with a subtitle that says "See You Space Cowboy.."

It's the show's way of saying "Goodnight" to the audience..

It is a cool way of saying goodbye to a friend too, or a possible replacement for "peace."

E1:
*End of Cowboy Bebop episode*
See You Space Cowboy...

E2:
Guy 1: See You Space Cowboy.
Guy 2: Later man.
