Oral capacity of the human mouth: a volume of 18 ml is not sufficient to become a full mouthful for anyone, but is approximately what most folks can comfortably hold within a single swallow of meat as an example, without choking on an esophageal food bolus impaction or rupturing the esophagus and causing an esophageal diverticulum of the pharynx:「head and neck」element with a marker stroke within denoting the reference spot.
As a stand-alone glyph meaning to grow towards night in Old English, EVENING extends from sunset to dark, otherwise known as one of the two TWILIGHT ZONE periods during each day, early morning and early night. May refer to the hours of early NIGHT and what was normally performed at that time of day by humans appears to depict swallowed amounts at SUPPERTIME after the hunting parties returned, related to various 'meaty body parts.'.
　Some scholars have suggested this glyph to mean EVENING because「clever heads」were able to trap or hunt MEAT, which humans then consumed at suppertime in the EVENING upon returning to the caves, eating the meat of a carcass as do scavengers such as vultures, and predators such as large cats after bringing down prey. Most clever animals will not place their head and neck inside something unless intending to eat it (and not to be eaten, as do many male humans). Most 「clever human heads」 did not wait until the following morning to eat meat, particularly during spring, summer, and autumn when natural refrigeration systems were not functioning too well. What is also being depicted are the ACTIVITIES that occurred in the EARLY EVENING, also depicted by the glyph 旰 with elements of a tonguing open mouth and downward thrusting, EATING MEAT of various types.
　Some sources suggest this glyph extends even further as a reference to the Moon due to visibility in early evening, but this glyph's most prevalent meaning as an element within other glyphs is「meaty parts, mooning (i.e., displaying buttocks).」Bonobos and other primates all exhibit proceptive lordosis mooning behavior today, as do many other species and lap dancers hired by club patrons. It simply is not likely referring solely to the Moon, Earth's only naturally occurring satelite that is sometimes visible in early morning, during broad daylight, and just as often is not visible during the early evening at all, depending upon the timing of its orbital phase moving steadily and evenly around the Earth. But a「moon」is always visible when someone bends over and displays his or her most meaty anatomical area.
　「Clever head sliding」「head sliding with no-longer-integrated foot emphasis within」elements also describe another joy of males in dynastic China after returning home and continuing throughout the EVENING HOURS. Given external meaning of SLANTED, SKEWED indicates「not even, in need of evening, off to one side」as it may have been with a head sliding inside a no-longer-integrated foot, a CONTAINER FOR A SMALL AMOUNT OF FLUIDS, to DIP something into something else with about one heaping tablespoon of stuff.
　「Bound feet were once considered intensely erotic in Chinese culture…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)
