Euphemism is the substitution of an expression that may offend or imply something unpleasant, with one that is more agreeable or inoffensive (which may be called a euphemism). Some euphemisms are intended to amuse, while others use bland, inoffensive terms for concepts that the user wishes to downplay. Euphemisms may be used to mask profanity or refer to topics some consider taboo such as mental or physical disability, sexual intercourse, bodily excretions, pain, violence, illness, or death in a polite way.
