In the South, you can say pretty much anything you want to about someone as long as the sentence also includes, “Bless His/Her Heart.” This way, otherwise harsh editorials can be softened:
“Bless her heart, she looks like a whore in that dress.”
“Bless his heart, but he’s dumber than a box of hammers.”
“Bless her heart, she really needs to get a grip.”
“Bless his heart, he’s gained a lot of weight in the last year.”
And on and on…
Try it — it’s fun!
