「Flinch, reflexively dodge incoming matter, deformed」with「rancid rod in copulation」needs no explanation as the motion of DREDGING.「Deformed and dangling stink with rod copulation」describes CLEARING AWAY OBSTRUCTIONS with a bougie from a bent penis discharging blue-green gleet and misshapen due to internal urethral scarring: TO CLEAN OUT A BLOCKED CHANNEL, and do not approach the discharging nozzle, as in TO QUICKLY TURN ONE'S HEAD AWAY and not be struck in the face with splatter, or, to not witness a bad scene such as a deformed fetus extracted during an abortion, or, a fetus deformed as the result of performing the abortion, as the case may be:「deformed child with action that will not produce offspring.」
Perhaps the source of the English expression「feeling blue」: elements are「squeezing bite, or, chopped with mattock」to create a「deformed child, one-armed or one-legged child (or both)」and「wasted effort.」The element「upside child, or, palming short leg」refers to a child who is or will become lost to the parents. Right elements combine as one meaning, to be「blue, stillborn」and as「inverted child」held「in palm bent and dripping, with much more than normal dripping」that suggests bleeding, possibly depicting the moment of parturition but a breech birth (with a foot or hand emerging first), dangerous for mother and baby due to blockage that was forcibly removed in order to save the life of the mother. A child who was not the proverbial bundle of joy, but a「bundle that was SHUNNED」(as depicted by the Japanese elements) due to a deformity, DREDGING, CLEARING A CHANNEL, REMOVING OBSTRUCTIONS, DIGGING A CANAL, NEGLIGENCE may arise due to a failure of the midwife to reposition the breech condition, or due to how the parents might treat such a disfigured child that survives, and that is with NEGLECT. Such a situation was certainly DISAGREEABLE for any parent and the child, and would often cause them to be ALIENATED, assuming he or she was not tossed into the nearest river (or worse) soon after birth, as infanticide was extremely common in the good old days of ubiquitous human cannibalism, replaced in modern times by abortion processes that still make it extremely common and more palatable for some folks.
