Japanese variant of the Chinese version 鄰,「human female front genitals」(not「backside, slurry muck-terraced slope」as in this glyph) with element that combines「sticky seed splat, jism」with「evening activities, inverted feet」: earlier Chinese versions included 炏, 䑞,「two flaming, two taut erections contained within evening inverted feet」that depicted two clients standing NEXT TO, ADJOINING, standing ADJACENT to one another, with each using one no-longer-integrated foot with the service provider lying on her backside between them both.「Flashing」is a Chinese euphemism for a 'quickie' as in a surreptitious sexual encounter lasting only a brief while, normally only long enough for the male to ejaculate, but wholly unsatisfying for the service provider, if unpaid. The later Chinese glyph 鄰 suggests being NEXT TO, ADJOINING, standing ADJACENT to the worker's female genitalia as jism is spurted down and across her supine torso. This Japanese variant, where dis-integrating feet was not commonly practiced, instead aligns「jism atop evening of inverted feet with naked backside buttocks」and if the service provider were kneeling in the lordosis position proceptively offering her rectum and vagina, then in fact her feet would indeed be inverted, soles upward.
　「Feet sneaking around to flashing flames」within a「village」(positioned in this glyph as the backside, anal orifice of a human) indicates a sexual encounter with a NEIGHBOR, NEXT TO your home, ADJOIN or ADJACENT to your own. Further note that「puckered」is apparently the preferred orifice when schtupping (ejaculation into a birth canal or other attainable orifice) your neighbor, or your neighbor's wife, in order to avoid your neighbors rearing a gaggle of children who resemble you uncannily (see related glyph 奧 meaning「deep inside, repeatedly bobbing head in neighbor's wife」). Putting it all together yields:「human backside with jism splat, puckered anus of village neighbor in evening with upturned feet」to indicate a tryst with someone living nearby, as an idea that seemed like a good one at the time but causing bad results within the village: using sex orifices on either side of one's own pit hole residence as the「next door neighbor.」
