In political discourse and protests, particularly related to the Israel- Palestine conflict, "Zios" has been chanted or used in hateful slogans, leading to controversies and consequences, including arrests and institutional condemnations, as seen in recent incidents at Oxford University and public demonstrations.

In summary, "Zios" is a slang term that functions as a harmful slur against Zionists and, by extension, often Jewish people, carrying strong antisemitic connotations.
