Slang for a citizen of your nation

[The Branches that Blow]

takje

[Arvenia]

Arvenians are called Arvies by immigrants.

[Yokerin]

Nasty-illegal-freeloading-fat-sacked-disrespectful-ugly-stupid-moron-savage-dirt-poor-naive immigrants call Yokerinians Yokes or an Oker. Very disrespectful. We hate it.

[Vallermoore]

A Vallie.

[Zhouran]

Zhouy, although, that's more of a derogatory slur than a slang.

[Petrokovia]

Generally, Petrokovians only ever use the full demonym (either "Petrokovian" or "Soviet"). Though, there are some terms used outside of the USSP. Most of them are considered at least slightly derogatory.

Petrov: Occasionally used by Exaequatio, especially more common considering the Slavic last name of the current Premier is Petrov. Is not used widely by any other nation. Not usually considered derogatory by most Petrokovians, though unless you come from Exaequatio, you may receive weird looks using it.

Ivan: Depends on context and who is using it. Sometimes those from non-socialist allied nations will use it just to refer to Petrokovia or a group of Petrokovians. This is the only acceptable use. If anyone from a nation who is not a close ally with the USSP uses it, it is considered derogatory (but just a low-level insult).

Дерзак/Derzak: Very derogatory name for Petrokovians. It is a Slavic derogatory name that first saw use by Chernarussians and their allies during World War I. It has since fallen out of favor in Chernarus. It is a combination of the word "shit" ("дерьмо"/"der'mo") and "Cossack" ("казак"/"kazak"). If you use this word, expect a swift punch in the face by most Petrokovians (who are normally peaceful, which should give you an idea of just how insulting/taboo this word is).

Petrokovians will usually address each other as comrade. While it is not insulting for a foreigner to use the term, it is generally considered strange for non-communist foreigners to use it, and unless you are a Petrokovian or a known communist, you may receive some strange looks (even if you come from a nation closely aligned with the USSP).

[Cult of Luna]

Moonees or Mooneyes (though they don't look like this).
Foreigners call them cultists for their unusual Religion.

[Thesybith]

Calling the citizens of Thesybith the Thesybithi can get a bit unyielding in casual conversation, so both foreigners and residents of Thesybith generally use the demonym Thesyian when referring to either the residents or topics relating to Thesybith.

[Reichsland]

The correct demonym for the people of Reichsland is Landser. Foreigners often call them Landies (pl.) or Landy (sing.)

[Caribica]

The term Carib was used by an Amerigan visitor to the nation in the late 1940s to describe the backwardness of the nations rural population, Carib was the name of the Native tribe which was known for practicing caniballism. The term is still used by citizens of more developed areas of the country such as Caribica City to describe citizens from the countryside.

[The Audesti Systems Federation]

Most of the time, the Audesti, including both its constituent artificial and organic peoples, are referred to by the official term, Audesti. The term Desti or simply Sti is sometimes used by non-Audesti races, though these are both highly informal and considered mildly derogatory among the upper crust.

A common, species-neutral term for anyone from the Systems Federation sometimes used by outsiders is Federal.

[Aleckandor REDUX]

Foreign observers, whether hostile or neutral or friendly, usually call Aleckandorean citizens in a civil atmosphere or soldiers in one pertaining to war as 'Leckers. If pertaining a reference to everyone and everything under the political and cultural dominion of the Confederacy, the term International 'Leckery is used, often in a very negative conspiratorial connotation. Very contextually neutral words of referring to an Aleckandorean, however, include 'Confederate', 'Confederalist', 'Confed', and 'AleConfed'.
