(No I am not talking comedy by african-american comics) this kind of comedy is born from taboos and subject matter that crosses the line twice. See New York Post taunt that freight-trained Jared Fogle as social justice warriors and snowflakes along with NoBama got pissed when twitter were hashtagging Five Dollar Footlong as implying it's not exactly a sandwich. This kind of humor is the type that can invoke a fist fight when taunted by bullies as you can imply the jokes about
genetic attraction, as in hindsight with a recent article showing up it's a bit 'grosser than gross' in hindsight. I employed this kind of humor when engaging Eric Hovind on
Creation Science Evangelism back in 2014 where I made a grisly one implying that the megalodon shark was in the water with Noah's Floating Zoo and one of the animals fell in the water when the fin was breaking the surface of the water. Or you can also use the film
Carnosaur to illustrate human-dinosaur co-existence really looks like as I coined this "The
Corman Retort."
The author of Gulliver's Travels is one of the your examples of
black comedy with the piece "
A Modest Proposal" as he might had inspired Edgar Allan Poe with his satire output,
Holden's Counterpart has tons of black comedy examples as the self-depreciation using the Italian slurs. The Fandom Writer was also my first approach with grim humor with dark horror elements.
