A fartdouken is a farting technique used to gross out a friend and amuse others. It is performed after the act of a fart by taking both your hands and cupping them directly in your crotch area to scoop up a good amount of gas, then close your hands together and raise up to your mid section in a hadouken pose, then expel into your friends face and yell fartdouken!!

Cupping a fresh fart in your hands and throwing it in the manner of a Hadouken.
