Did Zelenskyy use a cuss word for JD Vance under his breath during White House argument?

A visibly exasperated Volodymyr Zelenskyy apparently muttered a cuss word at US Vice President JD Vance during the unprecedented argument at the Oval Office, claimed social media users citing a viral video. It is not, however, confirmed whether Zelenskky actually said anything or whether the viral video was a manipulated one. According to social media claims, Zelenskyy called Vance “cyka” (suka), which in English translates to b***ch.
This apparently happened when JD Vance joined President Donald Trump in berating Zelenskyy and questioned whether he ever thanked Trump for taking the step in mediating the Russia-Ukraine conflict.
“I think it’s disrespectful to come into the Oval Office and try to litigate this in front of the American media,” Vance said, his voice rising. “You bring people on a propaganda tour, Mr President … Do you think that it’s respectful to come to the Oval Office of the United States of America and attack the administration that is trying to prevent the destruction of your country?”
“During the war, everyone has problems,” Zelenskyy replied. “But you have nice ocean and don’t feel now. But you will feel it in the future.”
“You don’t know that,” Trump interjected angrily. “You don’t know that. Don’t tell us what we’re going to feel.”
