Toilet humour, or scatological humour, is a type of off-colour humour dealing with defecation, urination, flatulence, vomiting and other bodily functions. Public reference to bodily functions is taboo in many cultures. This genre also sees substantial crossover with sexual humour, such as penis jokes.
Toilet humour is popular among children and teenagers, and despite being toned down to remove some of the more erotic components, it is still often seen as a rejection of taboos, and is a part of modern culture. This type of humor is generally considered to be low culture.
