「Palm covering a head」appearing in「loincloth」due to the excitement of a CITY MARKET initially filled with live meat bartered, traded, for sale/purchase, or as short-term rentals. Perhaps「covered with loincloth」as a necessary requirement for being allowed to enter an ancient MARKETPLACE or a CITY, with folks from rural areas initially being somewhat less concerned about covering the groin region.
　Or,「marker above the action of excreting」suggests how sellers if possible will treat most folks in a MARKET, and that anywhere in a CITY one is likely to be literally「shat upon from above」by pigeons or figuratively by the governing powers that be…perhaps literally, too, in the old days, since waste elimination from urban areas has always been a problem (the English simply tossed their feces out of windows into the street below…imagine that). Therefore,「emphasis on excreting」suggests not dumping indiscriminately, or at least an enjoinder to mind one's step since as Forrest Gump explained,「[sh]it happens」so curb your self.
　Marker above「rod down between spread legs」is a MARKET in a CITY selling sex slaves as fresh meat with shoppers inspecting the merchandise. Today we think of markets, or super-markets, as places to purchase food, but centuries ago each family formerly produced most all of its own food and did not buy it in a market (food spoils easily on hot days without refrigeration, canning, pickling, smoking, drying or salting, especially while returning home on foot or via horse and buggy).
　Scholars suggest that early MARKETS likely were places with sellers「palm down」holding「cloth」for trade, and that markets evolved larger and larger, finally becoming CITIES. Certainly a nice explanation, but most likely the first commodities bought, sold and traded were not textiles or manufactured clothing…after all, mechanized looms were not invented until 1678 A.D., and not used for manufacturing until approximately 1800 A.D. …Before that time, folks made their own clothing, along with providing their own food.
　For a very long time the commodities sold in a MARKET, and later in the first CITIES, were sexual activities, and slaves. Elements as「palm down on head in loincloth」may have indicated the desire to suppress excitement whilst strolling about window shopping…to be sure, the sellers employed a slew of techniques to pique buyer interest, just as they do today.
　To fetch the highest return on investment, displays were lurid and enticing, seductive and scintillating, resembling a 'no rules, just right' sort of 'anything goes, everyone comes' carnival atmosphere ('carnival' means 'meat elevated, displayed').
　「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.」

　Note that the really young girls (not the elder sisters, 姉 as 'marketable female') were not yet sold as slaves or prostitutes until fully trained in order to fetch the highest possible price, and since their small bodily orifices were still useful at home to the master, trainers, father, uncles, and brothers, not being fully stretched from overuse yet or from giving birth (see related glyphs).
