It’s all unpleasant and called diarrhoea
Stomatologists are experts focusing on the structure and function and the surrounding area of that part of the body through which the food enters. Proctologists are interested in the structure and function of the part of the body from where the waste comes out. And psychologists are interested to study why (mostly) very young children in particular are so interested in their own faeces and find it so amusing to examine what they can produce from their rear ends. When, however, what comes out of there is a semi-liquid, brownish and soft and sticky, smelly slush, it’s certainly much less amusing.
