Noun: A condition that forms from receiving regular, hard spankings (usually from a thick wooden paddle) over a long period of time. Tends to leave the buttocks leathery from built up scar tissue, and desensitized from nerve damage. It is much easier to take a spanking when one has a leather butt.
"I beat that ass so many times, that bitch got a leather butt."
