Toilet humour

Toilet humour, or potty or scatological humour (compare scatology), is a type of off-colour humour dealing with defecation, diarrhea, constipation, urination and flatulence, and to a lesser extent vomiting and other bodily functions.

Toilet humour is commonly an interest of toddlers and young children, for whom cultural taboos related to acknowledgement of waste excretion still have a degree of novelty. The humour comes from the rejection of such taboos, and is a part of modern culture.
