Any digestible product that sends signals to your body that you need to take a pooh instantly upon consumption.

Examples of Poohdisiacs: Cigarretes, Copenhagen, or any tobacco products, coffee, mexican food (especially local taco stands), many consistent nights of hard drinking.

Pooh + Aphrodisiac = Poohdisiac
I wouldn't smoke a cigarrete after eating Pedro's mexican food, they are serious poohdisiacs and their ain't no clean bathroom in sight.
