Black comedy, also known as dark comedy, morbid humor, gallows humor, black humor, or dark humor, is a style of comedy that makes light of subject matter that is generally considered taboo, particularly subjects that are normally considered serious or painful to discuss. Writers and comedians often use it as a tool for exploring vulgar issues by provoking discomfort, serious thought, and amusement for their audience. Thus, in fiction, for example, the term black comedy can also refer to a genre in which dark humor is a core component. Cartoonist Charles Addams was famous for such humor, e.g. depicting a boy decorating his bedroom with stolen warning signs including "NO DIVING – POOL EMPTY", "STOP – BRIDGE OUT" and "SPRING CONDEMNED."

Comedy is a genre of fiction that consists of discourses or works intended to be humorous or amusing by inducing laughter, especially in theatre, film, stand-up comedy, television, radio, books, or any other entertainment medium. The term originated in ancient Greece: In Athenian democracy, the public opinion of voters was influenced by political satire performed by comic poets in theaters. The theatrical genre of Greek comedy can be described as a dramatic performance pitting two groups, ages, genders, or societies against each other in an amusing agon or conflict. Northrop Frye depicted these two opposing sides as a "Society of Youth" and a "Society of the Old". A revised view characterizes the essential agon of comedy as a struggle between a relatively powerless youth and the societal conventions posing obstacles to his hopes. In this struggle, the youth then becomes constrained by his lack of social authority, and is left with little choice but to resort to ruses which engender dramatic irony, which provokes laughter.
