「Rod pulled out of shape」that euphemistically was defined as a the SNOUT OF A SWINE, or SNOUT OF A DOG by prior lexicographers, perhaps due to its resemblance to two long nasal cavities, or also likely as a clever allusion to due to the swine's ability unique among animals to burrow deeply into soil using only the snout, similar to the human male penis when erect, and a dog's affinity for sniffing anal orifices:「The snout of the Wild Boar is probably one of this animal's most characteristic features, and like other Wild Pigs, it sets these mammals apart from the others. The snout of the Wild Boar has a cartilaginous disk at the end, which is supported by a small bone called the prenasal, that allows the Wild Boar's snout to be used as a bulldozer when it is foraging for food. All Wild Boars have tusks on their bottom lips, although the male's are larger than those of the female, and actually curve upwards out of their mouths. More interestingly however, males also have a hollow tusk on their top lip too…」

　Glyph might have something to do with the English,「keeping one's nose clean」in various respects. Defined as a SWINE'S SNOUT, more than likely an old Chinese euphemism for a sick glans, a penis appearing to be「pulled out of the normal shape」curled or bent to one side, encrusted with「boogers」of dried gleet, dripping green-colored mucus. Refers to any flesh that has been「pulled out of the normal shape」for some reason, with a rod or other tool inserted in「horizontal motions」such as during acupuncture or other medical procedures: lancing a boil, draining a cyst, a bougie having a raspy tip for reaming from meatus to the prostate and bladder, and so on. The Chinese euphemism of a PIG'S SNOUT is the source of the English words 'booger' 'bougie' 'boogie' (anglicized from 'bougi'), and 'bogey' (closer to the pronunciation ぼうぎ bōgi in Japanese). Some suggest (炁) TAOIST CHARM refers to a「bougie」as a tool for reaming a penile meatus whilst in treatments for a gonorrheal infection to remove the gleet, and that both the English word and this treatment were derived from the Chinese: 矛炁 or 洩氣 or 矛起, or all three combinations.
　「Infection of the urethra is another cause. For example: Sexually transmitted infections such as gonorrhoea or chlamydia. …What is the treatment for urethral stricture? …Dilatation (widening) of the stricture: This is usually done by passing a thin plastic rod (bougie) into the urethra. This procedure may be done either under a local or a general anaesthetic. Rods of increasing thickness are gently inserted to gradually widen (dilate) the narrowed stricture. The aim is to stretch and widen the stricture without causing additional scarring. However, a stricture often tends gradually to narrow again after each dilation. Therefore, a repeat dilation is commonly needed every so often when symptoms recur.」

　A「rod pulled out of the normal shape」:
　「Peyronie's Disease,…also known as 'Induratio penis plastica,' or more recently 'Chronic Inflammation of the Tunica Albuginea (CITA),' is a connective tissue disorder involving the growth of fibrous plaques in the soft tissue of the penis affecting up to 10% of men. Specifically, scar tissue forms in the tunica albuginea, the thick sheath of tissue surrounding the corpora cavernosa causing pain, abnormal curvature, erectile dysfunction, indentation, loss of girth and shortening. …The disease may cause pain. Hardened, big, cord-like lesions (scar tissue known as 'plaques'). Or abnormal curvature of the penis when erect due to chronic inflammation of the tunica albuginea (CITA). Although the popular conception of Peyronie's Disease is that it always involves curvature of the penis, the scar tissue sometimes causes divots or indentations rather than curvature. The condition may also make sexual intercourse painful and/or difficult…」

　Both boar and dog snouts are euphemistic of a human male's erection: long and hard with an orifice at the tip: swine use their snout to burrow into soil seeking mushrooms (imagine that) and dogs poke their nose into an anus in order to identify the scent of the anus' owner for later reference. Other analogies remain fundamentally for the reader's fertile imagination.
　It has been speculated that boogie woogie (or bougie wougie, or booga rooga, or boogie oogie, and so on) blues music that may have originated in the piney woods of East Texas turpentine camps during the 1860-70s, which at first was characterised by a low, slow, steadily repeating bass rhythm akin to both a steam locomotive pistons scraping (to turn the wheels with a reciprocating rod in horizontal motion powered by the steam engine, not unlike the motions of a bougie) and to slow coitus, was a musical manifestation of the sadness and pain associated with penile reaming using a bougie, and the resulting oozing with a woozy feeling that accompanied this procedure (becoming "woozy from the bougie" morphed into "boogie-woogie" eventually with the "gie" sound mispronounced as a hard-sounding "g"). Brothels were formerly called 'boogie houses' for reasons other than as a place where sexual intercourse occurred with a slowly rhythmic beat piano player in the foyer, but also as a place where one contracted gonorrhea, 'the clap' with is slowly rhythmic dripping beats that caused the need for repeated bougie-boogie reamings and oozings…what other commentators miss is the fact that brothel houses of prostitution were called 'bougie houses' long prior to the advent of the music…and that the music was named after whores passing to everyone gonorrhea, not vice versa. This musical genre originated along the「Texas & Pacific Railroad, known lovingly as the 'Tits Ass Pussy Railroad' because of the large numbers of brothels near T&P tracks, and because prostitutes (the 'Railroad Ladies') often hitched rides on the T&P」　[　https://nonjohn.com/History%20of%20Boogie%20Woogie.htm 2019-06-16　]　Perhaps the source of the American phrase 'to be railroaded' suggesting a hurried process with questionable outcome. Today, obviously forgetting that the bougie house was where clap was contracted and the need for a bougie-boogie reaming became evident. See the lyrics to the original boogie-woogie tunes of the 1870s for further details, and patients being bougie-woozy.
