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

During a heated argument at the Oval Office, Ukrainian President Volodymyr Zelenskyy appeared to 'curse' at US Vice President JD Vance after being questioned about his gratitude towards Donald Trump. ​One user explained that 'Suka' -- the word that Zeelenskyy apparently said -- in Russian when used as an interjection expresses extreme frustration, annoyance and anger. It translates to 'b**ch' only when used as a noun. I have a degree in Russian philology so I kind of know what I am talking about," the user said.
