Frustrated Samurai
Rough sex using kendo-style armour. Not enclosed to any position, it excepts all. Usually involves spanking, biting and using a kendo sword as a sex aid (this is encouraged, but not compulsory). The couple/threesome/orgy/etc, then commit group suicide in the classic samurai style of a knife to the lower abdomen, this is due to the fact the penis can not win the battle against the vast variety of sex toys available. It is one of the most popular forms of snuff.
