"Zios" is a slang and derogatory term that is a shortening of "Zionists." Zionism is a movement for Jewish self-determination and the establishment of a Jewish homeland in the historic Land of Israel, originating in the late 19th century. The term "Zio" or "Zios" is often used as an ethnic slur against Jewish people or supporters of Israel and carries antisemitic connotations when used in hostile or prejudiced contexts. It is distinct from the actual meaning of Zionism, which is the political and cultural movement for the re- establishment and support of a Jewish state.

The term has been used offensively in protests and other settings to disparage or incite hostility towards Zionists or Jews. It is important to note that "Zios" as a word should be understood in the context of its offensive usage rather than as a neutral or positive identification.
