Star Party

From Slackerpedia Galactica

1. Take a huge blender
2. Add some stars
3. Add some female stars (Existence not proven yet... this could explain Dark Matter)
4. Blend
5. Drink and Enjoy the star party in your mouth

Or maybe not.

Usually a gathering of a bunch of amateur astronomers at a dark sky location to show off their telescopes and buy yet more toys.
