How do you say "Nope!" in United Arab Emirati?

As best I can tell, Oleg "Cricket" Sherstyachenko is a professional crazy person. His YouTube channel and Instagram page are filled with videos and images of him doing things in the high-up stories of the world's tallest skyscrapers that would make me slip into a fear coma. Case in point, this video of him leaping from ledge to ledge on the 43rd floor of a building in Dubai as though he weren't one misstep away from becoming a puddle of goo on the ground below.
