[Elements vary by font] Top and middle elements are one character in traditional fonts,「passing through」with「power」as in the effort, strength, and COURAGE, BRAVERY to make it all the way to the end (of what, though?). Some modern fonts depict elements as「down on all fours, shuttle-like movements back and forth, plugging muck orifice with power, effort, tense erection gasps, male」and the associated HIGH SPIRITS that ensue all around.「Male in lordosis posture」exhibiting sufficient BRAVERY「daring; not cowardly or timid」and courage to lower his guard that covers his ass: COURAGE is「the power or quality of dealing with or facing danger, fear, pain, etc.」(which may ensue whilst assuming the lordosis position) 　[　https://www.thefreedictionary.com/courage　]　
　Literally「down on all fours, shuttling movements」with「male」meaning COURAGE and BRAVERY may apply if not well-acquainted with the sexual habits of the partner in an era when infections can be easily transmitted by this behavior…clearly, 'male bowing on all fours' normally does not present an image of either COURAGE or BRAVERY unless down there for a reason that assumes significant risk, or pain. For example, during a bougie reaming session to rid oneself of urethral blockages caused by sexually transmitted infections:「rod reaming erection meat with tense gasps.」Scarring from sexually transmitted diseases can cause both a shortened penis and a bent or curled penis, especially when attempting to become erect. This scarring can be removed somewhat by reaming the urethra with a long, thin rasp file, known as a BOUGIE. Gonorrhea and other such diseases cause scar tissue to form within the urethra. A「bougie」(also spelled「bogey」or「boogie」) is a long, thin blade that is inserted into the urethra via the penile meatus that is used to thinly shave slices of scarred meat from within the passageway in order to remove scar tissue blockage formed due to gonorrhea and thereby restore the flow of fluids, be they urine, semen, gleet, blood, or all of the above (COURAGE and BRAVERY may apply at this time, too).
　「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…」

　One of the「Profiles in COURAGE」or the「RED BADGE OF COURAGE」? Someone dripping gleet constantly and smelling of putrid meat due to severe gonorrhea was not employable in most households or businesses, and often became beggars in street gutters, scavenging for scraps of food…unless present and recording the birth in the U.S.A. perhaps, as the author of「WE THE PEOPLE…[and so on]…」:「(6 November 1816, New York) Historic Darwin Award. A Founding Father of the United States, Gouverneur Morris was a signatory to the Articles of Confederation and the United States Constitution. He wrote the Preamble to the Constitution and has been called the 'Penman of the Constitution.' This intelligent and influential man died in New York City from an infection caused by shoving a whalebone into his urethra to clear a blockage!」(CAUTION: Do NOT try this at home! No DIY bougies, bogeys, or boogies, please. Perhaps more ignorance than bravery in this case.)

　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.
