[Elements vary by font and usage within other glyphs] Sources list this glyph as the "crooked short leg radical," whatever that is supposed to mean, but fail to mention that in dynastic China the penis was euphemistically referred to as the「short leg」in much the same manner as the U.S. military term「short arm.」「Arrayed rod segment, erection with bent penis」depicts a WEAKENED condition.
Note that some glyphs (such as 邥 and 兓) substitute 「raised leg, biting」(レ) in place of「bent penis」(乚) as it related to a service provider in China with no-longer-integrated feet, and「array of erections with a raised leg and feet no-longer-integrated」is perhaps the epitome of BEING LAME, ACTIONS WITH THE LAME, a LAME ACTION as it relates both literally and figuratively. Nor does a penis bent by a prior biting experience or an infection function too well, depicting a WEAKENED condition.
Perhaps a condition after being stung by a scorpion if the elements are interpreted as「hand」with「scorpion tail, appendage spewing venom.」
The man who boasted about himself as being The Greatest claimed to have abstained from sex prior to a fight, since「hand with penis」also WEAKENS a man temporarily for a spell, it would seem. Early human experience rich in both war and sex would have soon manifested this WEAKENED condition, as it also appears with other male animals banging heads and fighting to copulate with the female herd-in-waiting. Undoubtedly, ejaculation causes a male's testosterone level to physically decrease by volume and therefore perhaps WEAKENS a male, with testosterone as prime steroid material. Increased testosterone levels result in increased power and competitive aggression, which is one reason why athletes use steroids. Whether believed or not, the current Internet activity related to erotic sites and a man's「hand on his penis」in fact does WEAKEN his own「meat」at times contributing to erectile dysfunction, and a temporarily diminished desire for hunting meat while bar-hopping or by other means during refractory.
