What is the definition of Blackjack Macabre?

"Blackjack macabre is like a fancy deck of cards where the black jokers are the gravestones, the ace of spades is the skull and crossbones, and every shuffle feels like a macabre game of life and death. Picture this: 'The blackjack macabre deal broke, and I was left with a skeleton card and a whisper of doom.'"
