Hari Kari is the Norwegian version of the ever so famous Hara-kiri, mostly practised in Japanese regions.
Hari Kari is practised with a cheese slicer, or preferably a binder (both are Norwegian inventions). You stick the device in your stomach to commit suicide when you are tired of all the polar bears running around in the streets, and wearing woolen socks in the winter. When using binders, be sure to poke around thouroughly as it might take some time if you poke only once. For cheese slicer users, slice several times.

To impale one's self through the stomach, next to the spine, and to finish by pulling the blade through your side, therefore cutting off your main "chi" or energy channel. The purpose of which is to kill yourself with no hope of surviving.
