What is the definition of Mortality Fumes?

"Mortality fumes" is a rather morbidly poetic term that humorously describes the noxious, existential haze that lingers in the air after someone's life has tragically ended. It's like the foggy aftermath of a bad funeral, but instead of just dust and feathers, it's filled with the lingering scent of regret, unspoken words, and the faintest hint of a dying ember of hope.

Here's an edgy example sentence: "The mortality fumes from last night's karaoke disaster still hang heavy in the air, making it hard for me to find my last laugh."
