Kha Banh, real name Ngo Ba Kha, rose to fame in Vietnam in the late 2010s through Facebook and YouTube videos built around fan dancing, known as mua quat, flashy outfits and confident street slang. His clips were shared widely by young viewers, remixed into parodies and turned into reaction sounds even as he became a controversial figure. The audio survives in meme culture because the delivery is so distinctive, letting creators reference the whole persona, the dance and the swagger in one short, recognisable burst.
