Black comedy, also known as black humor or dark comedy, is a sub-genre of comedy and satire where topics and events that are usually treated seriously (death, mass murder, regular amounts of murder, suicide, domestic violence, disease, insanity, fear, child abuse, drug abuse, rape, war, terrorism, line-cutting) are treated in a satirical manner while still being portrayed as the tragedies they are. Black Comedy doesn't necessarily have to involve death -- anything tragic can be fodder for Black Comedy. A Kafka Komedy is a subtrope of Black Comedy in which the object of humor is abject failure.
