Geocide originated in Japan with most other means of suicide. It is now practiced world wide as an alternate to life.
Basically consists of slitting your wrists or neck with a sharpened thin section of any type of rock. This is generally used by Geologists who hate Geology so much they end it with the thing they love to hate; thin sections.
