>>28899649I've heard of a chinese idiom "to pull down your pants to fart", maybe it has something to do with that or some inversion of it?
Heres some guys quote online to expand on that
>" If someone does something completely unnecessary you can metaphorically say that they tūo kù zì fàng pì, that is they “pulled down their pants to do a fart. Women are always doing these pointless pull down your pants to fart type of things. That’s why they invented skirts."
