a) No. I’ve never heard this word before, and am surprised it is apparently an actual word, based on the responses here. What is its etymology? Never mind. I guess I can Google it.
Know it, it’s gotta be at least twenty years old, central US. (As in, I heard & used it as a minor twenty years ago–and considering my friends & influences it could be from anywhere in N. America or the British Isles for all I know.)
A: Kipe. (V. Uncommon). Can be used for non-stealing, eg, ‘kipe a nap’ ‘kipe some cookies out of the tin’.
B: New York (but my vocabulary is enormous and contains much antiquated slang)
C: 30s.
Oh, how funny. Zombie from the days before the polling software. And I don’t even remember what hypothesis I was testing (I think I was positing a NW or W US usage-- seems to be a bit broader than that including some of the NE. Wonder why I never returned? Think I was trying to graduate. . .).
