Daddy had more ways to say "I'm going to spank you" than he did ways to wail the switch. I used to wince at those euphemisms...
"Light up your tail"
"Paint your back porch red"
"tan your hide" **(a favorite of his)
"set your backside on fire"
"skin you alive"
"burn your britches"
"whoop your tail"
"tear up your hind end"
I'm sure I've missed about a hundred or so... And my hubby is from the South too and said the same kind of things to our children.
