"Fani Willis Says 'Bless Your Heart' To Jim Jordan"

"And as we all know, a southern woman saying 'Bless Your Heart' means 'Go Fuck Yourself.'"

As someone who lives in The South™, I can confirm that, in this particular context at least, it absolutely means "Go fuck yourself."

Bless your heart, GQP. Bless your heart with a rusty railroad spike.
