Toilet humour
Toilet humour or potty humour is a type of crude humour about defecation (pooping), urination (peeing), flatulence (farting), vomiting and other bodily functions.
Toilet humour is very popular with toddlers and young children, for they believe taboos about acknowledging wastes from the body still have a bit of novelty. The humor comes from such taboos being considered bad, and is a part of modern culture.[1]
