The act of skinning someone alive. It gets painful.
Ooo remember that one movie? Where that guy was impaled and and he and he was all hooks pulling his FLESH from his muscles? That one with the excoriation? Sexy.
The wearing away of skin through friction, usually in your asscrack when your wife and kids constantly swipe your credit card through it
Stop buying all of those bath salts and video games, i have rectal bleeding from the excoriation and its running down my leg!
