Not Worth The Skin On Your Back

A piece of shit. Pond Scum. Gutter Garbage. A person who is not worth your time of day. Have you ever heard someone promise something on their skin. It's the ultimate commitment to a promise. Someone who isn't worth the skin on their back is someone who constantly never follows through with anything, and is 100 percent untrustworthy.

Yet again you disappointment me and don't do what you say you are going to do. You are not worth the skin on your back. I'm done.
