Wet Jacob

First, your drink a liter of orange juice, eat a whole whack of Indian food and fiber cereal until full, you follow off by inducing 10x the regular dose of laxative.

Than, resting your head/neck on the floor, you use your hands / arms to hold your back and ass directly up in the air with your legs off to the side of your torso.

You than wait until the perfect moment of combustion. Pushing will all your might you spray a large fountain of diarrhea into your mouth and onto your face.

- the stream of diarrhea must reach at least over two feet of air to legally be considered a "wet jacob"
