In Chinese, suggested meanings relate to threshing and hulling grains, and simplified Chinese uses 'emit from person's orifice, v-shaped valley, a shape or form that contains other stuff' (谷) as a modern substitute. Japanese meanings refer to being an idle jerk-off, too lazy even to clean off the prior dried jism splats encrusted on one's legs before masturbating again.
　Elements describe the action of flinging stuff upwards randomly, such as when threshing cereal grains, tossing soiled leaves used to wipe one's anus after defecating (see 榖), getting lucky with yourself, being a jerk, passing time idly by masturbating with indifference, and/or publicly ridding oneself ofsome pesky accumulated gleet.
　「Penis on all sides with array of grain plants and stretched crotch skin」perhaps describes a male with a case of the clap in the process of changing his grain poultice and attempting to fling out as much gleet as possible before reapplying a fresh bandage, i.e., the ACTION OF THRESHING, flinging schmutz in all directions. Grains such as flax, barley, oats, rice, rye, and millet have been used since antiquity as components of a poultice, applied to infections for the purpose of drawing out the pus.
　Without further explanations, scholars simply say this is a swinging dong or clapper of a bell…a「flinging ding-dong.」Describes this same action of threshing as the process of extracting hulls from grain as THRESHING, and ultimately THRESHED CEREAL GRAINS ready for consumption (don't think too long about that, but other glyphs liken grain to gleet, also). Element meaning「extracting the crust」is perhaps derived from extracting fibers from hemp that involved cutting down the very hard, stiff, turgid stalks of hemp, allowing them to lay in the field while retting to swell and soften the outer hurds, becoming flaccid, and then beating the stalks to separate the fibers for making cloth, discarding the hurd byproduct as superfluous scrap. Quite possibly the lower-inside stroke of hemp hurds (冃) merged with 'sticky wad' (米) to form the element for 'grain' (釆). Modern interpretation of CEREAL GRAIN indeed does swell as it ripens, first with water, then with starch, and finally the moisture content falls in the grains to signal the harvest time. Japanese variant reduces the left element stroke count by one.
　Some browsers will not display this glyph using certain fonts…the actual glyph may possibly be seen within other glyphs as an element.
　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-to-single-people-find-a-sex-buddy-for-lockdown-coronavirus 2020-05-16　]
