What is Shidouken?
1.
A form of explosive defecation that is characterized by a person dropping his or her trousers, sticking their buttocks out, and firing a blast of concentrated feces propelled by one's pent-up, diuretic ki while screaming "SHIDOUKEN!".
This maneuver can be used as an attack of desperation, similar to a skunk's natural defense. When used in such a manner, a shidouken not only does damage to your adversary, but also stuns him due to the fact the he or she just got hit with a big ball of ass-flung shit.
