Black Comedy

Black comedy, is a sub-genre of comedy and satire where topics and events that are usually treated seriously are treated in a satirical manner, while still being portrayed as the negative events that they are. Typical targets are death, violence, crime, murder, suicide, insanity, disability, environmental disasters, political corruption, poverty, famine, disease, drug abuse, child abuse, animal abuse, rape, pedophilia, castration, cannibalism, war, terrorism, racism, sexism, homophobia, stereotypes, and line-cutting.
Black Comedy, however, doesn't necessarily have to involve death or violence; anything that's horrific, tragic, or otherwise dark and cynical can be fodder for it.
Black comedy usually derives humor from such topics either through cartoonish exaggeration (without entering the domain of uncomfortable realism) or sheer bluntness. A stellar example of the former is a scene in which an animal-loving assassin accidentally runs over an old woman's dog in A Fish Called Wanda; the reveal of the dead dog was originally filmed with realistic gore effects, which audiences found uncomfortable and unfunny. The scene was then altered to have the dog simply be flattened a-la Wile E. Coyote, which removes the disturbing realism and becomes darkly hilarious instead (said animal-loving assassin's inevitably horrified reaction to the event further aids in this).
What makes it different of other sub-genre of comedy is that the theme of the comedy gravitates towards topics that are considered to be "dark" and/or taboo (such as depression, death, atrocities, racism, poverty, etc.) 
A joke might revolve around, for example, a homeless man committing a string of murders so that he will get sentenced to death, a state that, properly tied up in appeals, is better than his former life expectancy and quality. Delivered correctly, it can be very funny, yet at the same time more than a little disturbing. If done wrong, however, the audience may be extremely offended, which is often used as an in-universe result.
