Soup Bum 

Once thought linked to chronic diarrhea, the condition is known to give ones stool a soup or broth like viscosity. Alchohol, deep fried food, and lack of solid foods can result in the unpleasent experience. Soup bum is known to leave the anal opening with what can be called "ring sting" due to the acidicty of the soupish substance and the force of which the soup exits the anal cavity.
