Refers to a ring of encrusted gleet and/or semen that often appears around the head of a woody, in particular during a dose of the clap, a bout with gonorrhea, or after masturbation without the compulsory clean-up: the pearls before a swine's snout (see 彑) appearing similar to another ring known as「booger crust」when it appears around and within the nostrils of a young child with nasal congestion caused by a cold virus who does not properly blow and clean his or her nose. A FLACCID TIP, a head dangling loosely and ringed by「encrusted pearls.」Chinese euphemism manifested in many glyphs refers to seminal droplets as「pearls」with external sources describing this glyph as a ring of pearls surrounding the corona of a head, or, the tip of a tapered flagging object (Japanese pronunciation) that is loose, dangling and flaccid…neither being a stretch to comprehend, with these elements of「method of doing something that will not produce offspring」「you and barren」among other colorful and possible combinations.
　Natural pearls are seldom spherical, appearing「uncultured.」「Cultured pearls」refers to pearls not grown naturally, but instead after implanting a starter 'spherical seed' into an oyster with no other sand or grit.
　A pennant was used first as a signal flag by ships and sailing vessels, with a referent to a 'pendant' having an elongated triangular shape, perhaps appearing to be「loose and dripping」as might a flaccid head of long, dangling wet hair after diving for pearls, not a task many cultured long-haired princesses would undertake.
　Note that the ancient Chinese were apparently rather blunt and frank when creating these glyphs, and the right element is linked also to「stillborn births」for obvious reasons. Investigating why「you, person of stillborn birth」also means「pearl-like bubbles surrounding a head as might a crown」remains for the reader to attempt, yet before doing so, please be advised that doing so is not advised (we did that…can't write it up).
　「Throughout much of recorded history, a natural pearl necklace comprised of matched spheres was a treasure of almost incomparable value, in fact the most expensive jewelry in the world. …Before the creation of cultured pearls in the early 1900s, natural pearls were so rare and expensive that they were reserved almost exclusively for the noble and very rich. A jewelry item that today's working women might take for granted, a 16-inch strand of perhaps 50 pearls, often costs between $500 and $5,000. At the height of the Roman Empire, when pearl fever reached its peak, the historian Suetonius wrote that the Roman general Vitellius financed an entire military campaign by selling just one of his mother's pearl earrings.」
