I once found a word on the Internet, but unfortuantely didn't write it down, and have yet to rediscovered it. The word perfectly describes the type of self-depricating, ironic , cutting but happy, wise type of humour that exists within my family and literary friends. e.g. A comment on a spate of gang killings recently: "One solution would be to supply them with free amunition and send the Police on holiday for a week... but that's just me." .The self-deprecating humour is in the phrase "but that's just me" intimates that you self describe that you are a heartless individual worthy of contempt BUT that actually is the way you feel about the situation. Does anyone know what the word is..? It sort of like Iconoclast or Black Ironist but, anyway it's been around since Victorian times "Coach Wit" and all that. There is such a word to describe the attitude-humour.... Someone must know it...? Thanks..!
One candidate is sardonic
humorous in an unkind way that shows you do not respect someone or something
Or Collins has
If you describe someone as sardonic, you mean their attitude to people or things is humorous but rather critical.
A slight shift of meaning with more humour in it is provided by wry
showing that you find a bad or difficult situation slightly amusing:
