「Crooked, substandard appendage spewing venom」is EVIL, BAD, and DIFFICULT TO USE OR DO, something everyone will DISLIKE, FALSE…and needs no further explanation.
　「Crooked-hearted, substandard mind or spirit」as the sub-class, BAD, EVIL.
　Or, the money-grubbing heart of a faceless, bloodsucking mercenary pit hole construction contractor. Top element may depict a hole in the ground (used as homes in ancient China and Japan) that is of substandard quality not in compliance with the local building code, in that the sides are not straight vertically: a pit or hole lined with stones for a home, with sides that curve inward on top (admittedly, slightly exaggerated in this element), is「bad」in that the top portion is likely to cave in (especially during a rainstorm) and collapse on top of the sleeping inhabitants, filling the hole at least partially with mud, stones and water, allowing mosquitoes, pernicious grain silo maggots and renegade scorpions to enter the hole, creating a situation of poor quality if the inhabitant and family have the desire to continue sleeping: from BAD to WORSE. Think about it. At first it was bad enough that you were sleeping in a hole in the ground, but now, the kids are screaming, the wife is nagging, the rainwater is pouring in, mosquitoes are buzzing in your ears, mud is falling into your corn flakes…and in the afternoon you can't watch the ball game because you have to patch up the 'hole' house again: BAD, a LOW-QUALITY SITUATION.
　「Spewing penis」with dynastic Chinese sexual service providers who indeed had five orifices available for short-term rental: her mouth, anus, vagina and two more created by mashing the bones in each foot. As depicted in erotic Chinese art, men in dynastic China masturbated by wrapping no-longer-integrated feet around an erect penis ostensibly to lower the risk of contracting a sexually transmissible disease or infection that often occurred when performing coitus within some sort of mucous membrane system of a female service provider, and, to gain hand-control over the pressure applied to the foot meat surrounding a weakened penis that functioned as a living cockring.
　「Bound feet were once considered intensely erotic in Chinese culture. …The process was started before the arch of the foot had a chance to develop fully, usually between the ages of 2 and 5. …Qing Dynasty sex manuals listed 48 different ways of playing with women's [no-longer-integrated] bound feet」(after removing the binding cloths, of course)

　「Viewing women as commodities [see 品] was also made customary from Song Dynasty (960 - 1279) forward, both in the suddenly expanded labor market and within relationships. Men could sell their female kin to slavery or prostitution, and frequently did.」
