A「befitting array of buttocks」as the lord's wealth and SEED STORAGE AREA, his bevy of concubines.「Stored corpulence」depicts a STOREHOUSE, TREASURY of a wealthy lord, and his concubines in whom he placed great trust (not to pass along an infection, not to clench him between toothed jaws, not to knife him through the ribs as he slept, and so on). Note the similarity of this glyph with that of「food」(食), simply replacing the element「concubines」( 比, 匕) with「orifice」(口).
「Person and array within anus」describes the COLON, LARGE INTESTINE having one function as a STORAGE SITE of ACCUMULATED feces prior to defecation, bowel movements that DISCHARGE AT ONCE, caused by peristaltic muscular squeezing actions of the colon walls.
「Person in front aligned」with「buttocks crack orifice」or「person to trust to do, place confidence in (㐆)」or「person in front with erection in tonguing mouth and orifice」all as references to a place that is trusted for one's assets, a STORAGE PLACE FOR SEEDS of some sort, an ACCUMULATION related to one's JEWELS and/or SEEDS, or buried WITHIN SOIL as an underground cellar. Usage also indicate something that will occur SUDDENLY, or cause WORRIED AGITATION, HASTINESS from bursting under pressure. Not surprisingly, glyph contains the left half of the「gateway」element (門) that seems to be merged with「person's doorway, buttocks crack orifice」(启), indicating the short-term rental of a service provider and/or any「person's gateway orifice.」
As an element within glyphs, indicates infected wounds, scarring, cysts, sickly paleness, skin ulceration, boils, and so on as symptoms of an unhealthy lifestyle, swollen areas of the body ready to burst and discharge fluids under pressure, such as pox pustules or accumulated gleet, oceans of thick green fluids, and visits to brothels.
Center element may be「buttocks, genitals」with an internal array or line, or「erection with bougie inserted」perhaps to indicate it is very difficult to open and release the contents, a place where something accumulates and is STORED prior to removal, a STORAGE AREA of concealed, secret, hidden items or material associated with jewels, seeds, soil, or all three—referring to stored fat, pus, tumors, or whatever within the skin and flesh of a human being's body. SUDDENNESS refers to the cyst, boil, pimple or infection SUDDENLY bursting, discharging and spewing the contents. Possibly depicting a「person in front」(a doctor, guards, someone trusted) so that the knowledge of what is inside remains tightly sealed, confidential.
