[Elements vary by font and positioning] emphasis on deepest point while「plugging an orifice with sliding head screwing」referring to the cervix is something the average male, in most cases, cannot normally accomplish using his erection unless the partner is quite small, or the penis is exceptionally long of course. Usage of this glyph as an element often pertains to a female masturbating with the aid of a pestle, horse-like penis-shaped dildo, a tool with which stimulation of the vaginal cervix is easily accomplished every time, at will: GREEDY and GLUTTONOUS for personal pleasure, open-mouthed conspicuous, subsequent torpor, and so on. Not much can be added by way of explanation if the upper element is「muck-filled plugged orifice」which suggests a penchant for anal necrophilia:「erection in the black and foamy.」
　Traditional elements depict an「erection」inserted as deeply as possible into an「open tonguing mouth」and「screwing, fully」in a deep-throated experience, one likely to kill the fellator by asphyxiation given sufficient time, and/or ejaculate semen into the lungs. Modern fonts depict「skull with head sliding up and in, filled completely blocked plugged by screwing.」Either way, no regard whatsoever is held for the fellatrix: DEPRAVED, VILE, TO DEBASE ANOTHER, VULGAR in the extreme by a GREEDY person GLUTTONOUS for personal pleasure in total disregard for another human life, considering that human as meat, a mere sex slave INFERIOR and replaceable with a subsequent purchase, to be disposed of, if killed, and so on and so forth.
　Whether the perpetrator described by these elements caused the death of the victim or the head being used for sex was already dead or decapitated, it is difficult to escape the conclusion of someone engaged sexually with a warm dead person, a cold corpse, or a portion of one. Not many human actions are more VILE, BASE, LOWBORN, VULGAR, COARSE, CRUDE, MEAN, SHABBY, GREEDY, CONTEMPTIBLE, TO BE DESPISED, DISDAINED, TO BE SCORNED, or ABASING than NECROPHILIA in all its various incarnations.
　「Singular accounts of necrophilia in history are sporadic, though written records suggest the practice was present within Ancient Egypt. Herodotus writes in The Histories that, to discourage intercourse with a corpse, ancient Egyptians left deceased beautiful women to decay for 'three or four days' before giving them to the embalmers. Herodotus also alluded to suggestions that Greek tyrant Periander had defiled the corpse of his wife, employing a metaphor: 'Periander baked his bread in a cold oven.' …Hittite law the 16th century BC through to the 13th century BC explicitly permitted sex with the dead.」

　Before decrying, note that cannibalism, torture until death, and necrophilia were portrayed in the original Snow White and the Seven Dwarfs by the Brothers Grimm in their children's tale.
　And apparently, necro-feelie-ya is still alive and well in the 21st century:
　「A Los Angeles police officer has been charged with a felony after footage captured by a body camera allegedly showed him fondling a deceased woman's breasts.」

　Without a doubt, the Irish also have knowledge of their own to pass along in these trying times:「Masturbation will not spread coronavirus, especially if you wash your hands (and any sex toys) with soap and water for at least 20 seconds before and after.」Nonetheless and regrettably, unlike in dynastic China, it must be undertaken alone to truly be a preventative countermeasure but still achieve the desired result with some degree of safety.

　The Dutch, too have the same solution—it seems masturbation has become mainstream in the media the world over due to the coronavirus (it has always been 'the main stream' in reality, albeit covertly for most folks):
　「'Don't have sex with your partner if they have been isolated because of (suspected) coronavirus infection,' the RVIM says. 'Sex with yourself or with others at a distance is possible (think of telling erotic stories, masturbating together).'」

　Needless to point out perhaps, but Chinese shamans from antiquity hit upon the same solution as a pandemic preventative countermeasure, honed for ultimate client satisfaction by utilizing naked females with no-longer-integrated feet as masturbatory sex buddies available for short-term rental with erotic visualization of live prepubescent female genitalia engaging in autoerotic stimulation herself, as a solution to the same problem facing us now, but in pre-Internet days.
