Some insist this glyph describes collecting firewood by placing pieces in one's removed loincloth for bundling, hoping and expecting a fire that evening (?)…or, simply homosexual loincloths hoping and expecting some flaming action while in heat.
It is significant that as the earliest Chinese variant, 㠻 uses elements of「old men, fagot (faggot)」and a「rod within spread legs, loincloth.」Ancient GREEKS were proudly homosexual. Indicates PHENOMENAL DESIRE, to BEG FOR, IMPLORE, YEARNING.「Faggot with a loincloth」(i.e., wearing one rather than being naked) as something likely to be SCANT and INFREQUENT since ordinarily one removes one's loincloth prior to engaging one's rod within a set of spread legs, depending upon one's orientation. DebunKanji does not state a moral opinion regarding the use of the term FAGOT (FAGGOT) to describe HOMOSEXUAL MALES, but is simply explaining how and why the use of the term originated, and the glyphs behind that usage. As made clear by this and many other glyphs, homosexuals were not an infrequent phenomenon historically…quite the opposite. SCANT means「barely sufficient, falling short of a specific measure, inadequately supplied.」…NEVER ENOUGH TO SATISFY THE DEMAND.

As SCANTILY CLAD, both in reference to INFREQUENT wearing and small size, somewhat akin to a bush-man and his attire, or lack thereof. RARE also refers to「red」as nearly raw, often bloody heated meat, how supper might be ordered.
RARE and RAREFY, RARIFY refer to being scant or not often located as the color of rubies, but also the color of genitals in heat within a loincloth, that ember burning at the tip of a fagot (faggot). Rare and noble gases refer to chemical elements that do not combine readily with other kinds, and generally remain only with other molecules of the same type.
However implausible the suggested renderings of these elements may be, in the good old days「woven cloth in hand」or「weaving motion of hand in loincloth」as ass-wipes were only used by the very wealthy nobles but functioned well and so were DESIRED of course (serfs used a large leaf, or, did without). Elements could be「incontinent old man with dementia, infantile brain with hand in loincloth」and in fact many male infants and old men reflexively place one thumb in the mouth while the other hand fingers the glans penis in a diaper (or「incontinency pad」if you prefer), a「weaving hand in loincloth」or「much whacking of rod in spread legs」as a sort of trademark of a male human, from infancy to dementia, a lifelong experience (寿).
