「Shafts emerging with homosexual someone」and used for a range of meanings, but such a scene as a homosexual performing fellatio with a few shafts simultaneously would be OBVIOUS, as might「shaft heads sliding in feces with open-mouthed stupor」and likely result in STRINGY THREAD-LIKE STUFF CLINGING TO AND ADORNING THE UPPER BODY. Related to BOOKS and AUTHORS since in the old days, books were actually long scrolls of vellum or parchment (skins) and later loincloths or long cloths with two woody stiff shafts attached with skin on both ends and coiled, scrolled, with the two woodies appearing to be inserted into holes formed by the「rolled skin tubes」(see 本),「woody shafts emerging of homosexuals.」
In old Chinese, also meaning TO CATCH an illness, and, an ACTION STILL IN PROGRESS, to SUFFER from COMING INTO CONTACT WITH disease that causes a BURNING SENSATION, likely a description of anal or pharyngeal gonorrhea:「Some men with gonorrhea may have no symptoms at all. However, common symptoms in men include a burning sensation when urinating, or a white, yellow, or green discharge from the penis that usually appears 1 to 14 days after infection. Sometimes men with gonorrhea get painful or swollen testicles…Symptoms of rectal infection in both men and women may include discharge, anal itching, soreness, bleeding, or painful bowel movements.」

Initially the fame of a great AUTHOR, and authors often used pseudonyms (that「homosexual someone」reference), then to the LITERARY WORKS themselves, and finally ARRIVING ON THE SCENE perhaps with a flourish at a party or the opening of an opera and everyone would TAKE NOTICE, quite OBVIOUS and REMARKABLE.
Note some scholars suggest that this is the old version of the glyph that has now morphed into「looking under a sheep's tail」(着, see that glyph for an explanation of why) and if so, the topmost element might be「horns, raised on both sides, or, spurting in a stance.」…the suggested replacement glyph also refers to anal intercourse (or its prevention) of another sort, so the scholars may be right about this one.
Additional meanings are to COVER UP with clothing, APPLY OINTMENT to a festering lesion, to GILD or APPLY VENEER and cover what is underneath, to GIVE A BAD NAME or SULLY A REPUTATION, all related to that burning sensation. ACTION STILL IN PROGRESS is related to WEARING UPPER BODY CLOTHING but perhaps not any lower body clothing…?
