Heard snoopy.. but more often its “nebby” around here..
The thing is, not only have I never heard that outside the name of a comic dog, but even allowing for it being based on some other word, I still got it wrong.
I assumed maybe “snoopy” meant NOSY, you know, snooping around into other business.
But no,it means what we call “picky”. Finicky. Sigh.
