To look at the stars; Stargaze.
I like to astron on the roof of my house at night.
The state of mind which can only be achieved after one or more gravity bong hits out of a container equal to or greater than the size of a 32oz Gatorade bottle. When you have reached "astron", the following activities are not recommended:
1) Watching Salad Fingers
2) Driving anything more dangerous than a tricycle, and even then only under supervision of someone of sound mind and body.
3) Texting, IMing, or engaging in any form of social networking beyond two syllables.
5) Investment Banking
We were all astron last night dude. We're gonna need more shit.
