Neutral to moderately offensive word for unimportant and uninteresting town

There are several idioms that come to mind, but they also imply that the town is small:

One-horse town

One-stoplight town

Wide place in the road

Hick town, Hicksville

Jerkwater town

Podunk

Several thoughts:

One-horse town: An old-fashioned expression referring to a small, boring, backward place.

Backwater: A town where nothing important ever happens and progress rarely occurs.

Jerkwater town: A location with little to offer in terms of worthwhile sites or basic conveniences.

Podunk: A fictional locale defined by its insignificance and relative inaccessibility.

Back of beyond used in the figurative sense may suggest a dull, unimportant place:

• A place that is remote or unsophisticated.

For me, the term burg comes to mind.

Random House Kernerman Webster's College Dictionary:

Informal. a small, quiet city or town.

This has the possibly unfortunate fact that in some contexts it has exactly the opposite connotation. The American Heritage® Roget's Thesaurus:

Informal. A large and important town

Also consider: the sticks. McGraw-Hill's Dictionary of American Slang and Colloquial Expressions:

and the sticks n. a rural or backwoods area. (Always with the in this sense and always plural.) You hear a lot about how things are in the sticks. They’re worse.
