Part of the phrase, "the last nail in the coffin" or "another nail in the coffin". Equivalent to "the last straw". A very old phrase.
He cheated on her again? That's got be the last nail in the coffin.

The death of the rapper, Benzino! Eminem fucking spit bar-after-bar right at his throat, each diss more savage than the last! The line where Benzino just died instantly was:

Slap my mom! Slap the fuck out of her
She can't sue you, she wouldn't get a buck out of ya
'Cause you're broke as fuck, you suck, you're a fuckin' joke
If you was really sellin' coke, well, then what the fuck
You stop for, dummy? If you slew some crack
You'd make a lot more money than you do from rap

It was too much for Benzino to handle! RIP Benzino!

Get the nail in the coffin mug.
A Malaphor, or an idiom blend, combining "hit the nail on the head" (to do something exactly right) and "another nail in the coffin"(something that will harm or destroy someone – e.g., cigarette) to mean someone succeeded at doing something that may lead to their demise or the demise of another or just that they did a great job at something that they probably shouldn't have done at all.

Best used sarcastically.
"You did a great job of pissing off your ex. Really hit the nail on the coffin back there."
