In the past 35 years, my mother had called a number of the siblings' friends "droogs" (and some of her own I'm pretty sure). We all believed she had invented the word. Today I learned that "droog" is a real word from "A Clockwork Orange". It's Nadsat for "teen" though in my mother's version is means, "may do drugs, has bad posture, poor manners and is not-for-you".
In summary, it's real-ish.
