'''' () is a Polish neologism and an ideological concept (ideologeme) literally describing the rule of the Law and Justice party (PiS), derived from the names of Polish politicians, brothers Jarosław and Lech Kaczyński. As an ironic or propaganda term, it is used by opponents of the political groups of the Kaczyński brothers, while considered inaccurate and offensive by PiS supporters. Although in recent years the phrase has been reappropriated by supporters of Law and Justice and is sometimes compared to Trumpism in the United States.
