An English phrase which has similar pronunciations with a Chinese dirty talk: fang nimade pi, which literary means 'fart your motherfucker' or 'fart your mother's fart'. Basically a rude expression of 'go to hell' or 'fuck off'.

The origin is under one of Donald Trump's tweets. He claims that the Covid-19 is 'Chinese virus', and Chinese people used this word to present their disdain for him.
