This word means the same thing as "trippy" except it is used to describe something that happens when someone isn't high. When something sounds or looks so wierd and amazing that it seems it can't be described chimpastical is the word to use. This word was originated from a noise made in a techno song.
The noise playing in the background of that song is chimpastical.
