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
