Refers to something that is MORALLY REPULSIVE:「flow」from or with or in「two」「bound feet」of a Chinese sexual services provider/concubine or「flow with widening damage, deficit.」…note the Chinese variant (污) clearly uses elements of「flow, fluids with two no-longer-integrated feet」or more likely「flowing fluids twice with no-longer-integrated foot」(uncleansed: see 弗) that describes SQUALID conditions for the second client following another and experiencing a high-risk situation for the transmission of infection in the first guy's SORDID schmutz still SMEARED within the foot meat, as「two rods, the second rod with fluid flows within foot that is no longer integrated.」「Flow from stinky feet」as SQUALID stench.

　「The tightness of the binding meant that the circulation in the feet was faulty, and the circulation to the toes was almost cut off, so any injuries to the toes were unlikely to heal and were likely to gradually worsen and lead to infected toes and rotting flesh. If the infection in the feet and toes entered the bones, it could cause them to soften, which could result in toes dropping off. Although, this was seen as a benefit because the feet could then be bound even more tightly. Girls whose toes were more fleshy would sometimes have shards of glass or pieces of broken tiles inserted within the binding next to her feet and between her toes to cause injury and introduce infection deliberately. Disease inevitably followed infection, meaning that death from septic shock could result from foot-binding, and a surviving girl was more at risk for medical problems as she grew older.」
