rude slang Creamed chipped beef (processed beef that has been salted and dried, served in a white sauce) on top of toast. A traditional staple of military mess halls, where the term is often used. Primarily heard in US. I know it isn't a very glamorous meal, but one of my favorite meals growing up was always shit on a shingle! After eight years on active duty, I've had more shit on shingles than I care to recount.
