SOS n. Shit on a Shingle.
In the military this refers to creamed chipped beef on
toast.
In the Southern US, a similar dish is made consisting of chunks of fried ground beef in a thin cream gravy,
served over
toast. It is associated with poverty, because it is cheap, packed with calories, and filling.
"Hey mama, is that SOS ready yet?"
"Naw, we're out of PET milk, somebody's gonna hafta
