“Bless your heart” means I was “raised right” and can’t call you a dumbass to your face.
“Raised right” means you were in church at least twice every Sunday and are still scared of you little bitty, old mama. You have to “Ma’am” and “Sir” folks till the day you die, or Mama will be “hurt.” You don’t want Mama to be hurt. You’ll be “lower than a snake’s belly” till one of the other kids messes up.
If a girls “smears” on too much lipstick folks might say her face might look like a “chicken’s butt in pokeberry season.”
If you’re not treated right, you’re sucking on hind tit.” If things are great, “you’re happy as a dead pig in the sunshine” or a “pig in slop.”
You have to wave at everybody in the neighborhood, and speak, or at least nod to everybody you meet. It doesn’t matter whether you know them or not.
This is just a start. If you are headed South and need some help, you know who to call.
