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.
Josh: "shi...dou...KEN!!!!!!!"

Travis: "..."

Travis: "DUDE WHAT THE FUCK!?!?!?"

Josh: "Shidouken, baby"

Jul 12 Word of the Day
The horrible moment when you realise that you have accidentally done something very slightly wrong which has very bad (usually embarassing) implications for you. This is typically the moment of realisation that you just sent a dirty text message to a close member of family, typically your mother, rather than the intended recipient.
Message: "i'm free this afternoon so come over and fuck me senseless, my parents will be out all day"
Recipient: Mum
