Are we reading the same thread? Nowhere in the comments does OP ask for UK-specific terms. OC said “the sticks” doesn’t mean poor (agreed) and mentioned what the UK. OP accepts then asks for a better term and I replied with my anecdote.
“Backwoods” is what my friend calls the poor part of “the sticks” so I believe my reply was relevant
So it seems! Oh well, no hard feelings here
