Toilet humour, or scatological humour, is a type of off-colour humour dealing with defecation, urination, and flatulence, and to a lesser extent vomiting and other body functions. It sees substantial crossover with sexual humour, such as dick jokes.
Toilet humour is popular among a wide range of ages, but is especially popular with children and teenagers, 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. Examples can also be found in earlier literature, including The Canterbury Tales by Geoffrey Chaucer.
Toilet humor is common in television shows such as Beavis and Butthead, Ren and Stimpy, Rugrats, Rocko's Modern Life, Aaahh!!! Real Monsters, Ed, Edd N Eddy, South Park, Family Guy , The Simpsons, Futurama, Rick and Morty, Adventure Time, Regular Show, American Dad!, Fairly Oddparents, SpongeBob Squarepants and Kenny Vs Spenny.
