In the US, in most states, getting caught or recognized is enough to put you on the sex offender list. Even if you’re in private. (Again, in most states.) And that means you can no longer move into a new home without informing all your neighbors that you’re a sex offender for the rest of your life, among other penalties. There’s no difference to the US between this and people who actually do sexual crimes when it comes to this punishment.
So called because the toast in military kitchens were nicknamed shingles, as in roofing tiles. Evocative of bad cooking, which I’m betting was rampant.
Honestly, shit on a shingle (s.o.s. appropriately) is better than it sounds, even when not referred to under that name. But it’s definitely a comfort food. It’s not good for you, it’s just creamy, beefy, and starch. Inoffensive, cheap, and easy to make in bulk. (Kinda want some now.)
