Tucson, AZ has often been referred to as “Too-Stoned.”
Since this has been resurrected, I’ve heard Sacratomato from someone who lived in Fresno.
I’ve also heard De-twat for Detroit.
I think the use of that word is the sole remaining crime for which California still imposes the death penalty.
North Carolina has a Fayette Nam as well, officially known as Fayetteville, and the home of Fort Bragg.
I’ve heard of Chapel Hill being referred to as Chapel Hell, but I’m not sure if that’s the city proper or UNC’s flagship campus.
Don’t know if it’s just the locals, or the surrounding states that call Mass. “Taxachusettes.”
When I lived in Sacramento (a long time ago), I remember hearing Sacratomato all the time on the radio. They’d mention the weather or the traffic in “Sacratomato”. Maybe it’s gone out of fashion.
I’ve referred to “Butt, Montana”, but it’s not really fair. The stinking filthy hole in a butt serves a useful purpose.
Jesse Helms was such a fan of Chapel Hill he said the state did not need a new zoo, they should just put a fence around Chapel Hill.
And he called the coed dorms at UNC “State supported cathouses”
You must be confusing Houston with Stinkadena (Pasadena), known for its abundance of stenchy refineries and petrochemical facilities.
Hell’s Half Acre was actually where the Ft. Worth Convention Center and Water Gardens are today… Sundance Square was further north- up by the river.
Ha, my niece and nephew heard that in 1st grade. My niece was especially proud to ask us what Moorpark is spelled backward. It’s kinda cool for little kids who are just learning to read.
Also Chiberia because of the weather in winter
It’s a slam based on the perception that _tucky denotes a backward/trashy population. Some residents of Columbus refer to the town of Grove City just to the south as “Grovetucky”.
Another deprecating nickname: Indianapolis hasn’t classically been called “Naptown” because people thought it was an exciting place.
Local TV news anchors and reporters there still refer to Baltimore as “Charm City” in feel-good stories. I’m not sure how they keep a straight face, because it’s usually about ten seconds after reporting on the latest beating, murder, armed robbery, drive-by shooting, or city government scandal.
And another one (which I won’t post here, I’m sure it would at least merit a warning if not worse), because it’s got a large population of people of African descent.
Hm. Can’t imagine what that could be.
Worse than Chiraq and Chiberia for me is New York Lite. Talk about insulting.
Not a city, but I hear Missouri being called “Misery”
If I had to invent one for Sacramento, I would have gone with Scatramento.
Logan City, Queensland (just south of Brisbane) has traditionally been a lower socioeconomic area and is frequently dubbed Bogan (the Aussie equivalent of “trailer trash”).
But honestly Australia has so many bizarre place names that most don’t even require a derogatory nickname, including an actual Bogan Gate in outback New South Wales (enjoy this delightful video tour that went viral a few years back).
See here for extensive map listings that will have you laughing for hours. 
Back in the 1960’s I lived in Cuyahoga Falls, Ohio, a suburb of Akron. It was known as (1) solidly middle class and (2) for having no black citizens (and took actions to keep it that way). So it was called at various times “Caucasian Falls” or “Cuyahonky Falls”
BTW, I looked at Wikipedia and the black population has climbed to 3.3% of the total population. So progress has been made–very deliberately.
In England (not cities; we have a stricter definition of those, so these are just places):
Bracknell is sometimes called Cracknell
Bradistan for Bradford, because of the large number of people of Pakistani descent there.-Istan is added to a few other places, though I could think of them right now
I’ve heard Basildon called Basildon’t. But it’s also know, ironically, as Basvegas. I think Glasgow is also nicknamed Glasvegas sometimes.
Hove, near Brighton, is often called “Hove, Actually,” because until that nickname became popular that is genuinely how residents used to refer to where they lived when everyone assumed they were in the slightly less posh Brighton
Edinburgh - Auld Reekie, referring to it smelling
Tottenham in London is sometimes called the 'Nam, and so is Dagenham, but they’re not serious nicknames although they’re slightly rough areas. Posh Cheltenham is sometimes called the 'Nam in a very ironic way.
A part of the West Midlands comprising several different towns is called the Black Country. It’s an official name not just a nickname, but although it does have a higher than average number of black residents, the nickname is from the number of factories there used to be there, and all the soot they used to create. It’s sort of been reclaimed as a name but the origin was definitely disparaging.
When I was in Guatemala in the 70s Chichastenango was referred to as Gringotenango because of all the tourists. Here in Panama there are any number of “Gringolandia” developments for ex-pats.
Not a city, but I’ve heard southern Mexico referred to as “Guatepeor,” as being even worse than Guatemala (mala = bad, peor = worse)
I was told a variation of that as a rah-rah chant: “Norfolk! Where we neither smoke, nor drink, nor…f**k!”
