The Void is the type of feeling one gets after finishing a really good video game/book/tv show/movie. The piece of media was so good, it leaves a void in you, leaving you wondering if anything else will ever fill the void.
The mystical place one encounters when enough THC is consumed. Usually accompanied by extreme warping of time, philosophical/existential thoughts, loss of ego, and inability to move.
Dude this stuff is insane, I took 2 hits and I'm already in the void.
