[Japanese variant: see 轉] today, perhaps a vehicle in motion with ROTATING wheels.「Rolling wheeled vehicle」with「billowing vapor, cloud, stench」is perhaps the dust cloud behind a moving cart on an unpaved lane two ruts, or today, the exhaust fumes belching from a fossil-fueled automobile ROLLING along.
Alternatively,「screwing, plug orifice, rotate」with「two short legs」or「twice loose and dripping」also indicates a TUMBLE, ROLL in the hay, GYRATING, REVOLVING ACTION of two ruts in night soil. One way or another, it appears the glyph is closely related to ruts in soil and rutting in soil, an apparent coincidence of English terms that is not actually coincidental in the least.
「Three screwings in line for orifice with turbid-flaccid loose dripping stench」in a「military vehicle with intercourse」「many screwing in orifice with [army] dogs howling moaning and screaming」certainly sounds a bit like a MEAT WAGON used as a station for 'comfort women' in ROTATION, GYRATING, REVOLVING SEQUENCE OF ACTIONS, THROW DOWN, TUMBLE, FLAILING, ALTERED MEANING, REPEATED TRANSACTIONS, A TURN, A SHIFT and so on.
「Billowing vapor」element some suggest is a remnant of a「rotating arm」protruding from a drop spindle of a loom. Formerly in Chinese (轉), right element of「spinning concentrated」with the top element of a spinning drop spindle of a loom over「taking a pulse with squeezing careful hands, measured.」…nonetheless, the glyph also means「screwing, plugging orifice, and then again, after being grabbed by one's father in a rutting action」so you need to decide for yourself what it refers to. The drop spindle gathers multiple hanging or dropped single silk fibers. A single silk fiber from one cocoon averages 1,000 meters in length (3/5 of a mile), a very long, thin, strong fiber. The mass of cocoons GYRATES and TUMBLES over and over as the fibers are unwound, making them look as if the caterpillar within each cocoon were still alive. Fibers collected by the extended arm and spun into a single thicker thread with a ROTATING MOTION. Clouds are also said to「roll in, tumble」at times due to the billowing motion of the gases. These latter suggestions admittedly require a greater leap of inductive logic than simply grabbing and rutting twice, causing「billowing vapors of a screwing short leg.」
