「Repeatedly loose dripping stench while reaming muck-filled plugged orifice」clearly would LEAVE A MESSAGE for most folks, and required DETAINING the head, HOLD IN ONE PLACE, FASTENED, CONFINE, KEEP the beast from bolting during a painful medical procedure with the bougie shaman witchdoctor. While in the West an infected penis is referred to as a 'short arm,' the Chinese euphemism is the 'short leg,' or, 'third leg' as a「raised leg.」
Some say top elements resemble「repeated mattock point biting」with「reaming」(marker stroke emphasizes the「point」) that perhaps refers to the repeated movement of an animal powering a plowshare to till and break up the soil of a「rice paddy」as if there were many mattocks being repeatedly wielded by humans. Conceptually a plowshare cutting a paddy, reaming in muck hole, and「bit filling a mouth orifice」depicts DETAINING the head, HOLD IN ONE PLACE, FASTENED, CONFINE, KEEP the animal focused and working while plowing into soil. Scholars say that the top elements were a「mouth bit」(戼) for cattle or yak, or water buffalo, or a gonorrhea patient to bite down on to prevent「rowdy screaming and hollering accusations with erection and rod movements.」
In some glyphs and with some fonts (for example, 鎦), the top elements are drawn as「slit, passageway to the ovaries, bunny」(卯), which is significant when considering the lower element as a filled muck hole and the need to CONTROL MOVEMENT, DETAIN, HOLD IN ONE PLACE, FASTEN, CONFINE, REMAIN, STAY with the subject in this case (see the glyph meaning「sequence」番). Normally, sane folks will STOP AT, GO NO FURTHER THAN the anus once access has been achieved, since tonguing, tit-fucking, and vaginal intercourse subsequently during the same session are considered by some to be unpleasant, with added meanings of「to prevent, to suppress, to hold back, to relieve, to dissuade, to forbid, to prohibit exiting.」…although, subsequent use of no-longer-integrated feet likely did not present the same problems until the client changed, which was another reason for the popularity of no-longer-integrated feet, and that may be the true meaning of the emphasis point in the top-left element: TO STAY AND REMAIN WHEN NORMALLY ONE WOULD NOT. See 溜
Nevertheless, with all due respect to the scholars, the elements also are「repeated raised leg, dripping」with「reaming, erection in no-longer-integrated foot」「filling that orifice, muck hole」which describe DETAINING a service provider, HOLD IN ONE PLACE, FASTENED, CONFINE, REMAIN WITH and STAY, KEEP from escaping by any means necessary, and continuing to ream in one place or another, KEEPING the animal focused and working after plowing into soil.
