「Stinky, rancid meat」or「loose dripping meat」might attract flies, then be a place for nourishing maggots.「Loose and dripping meat」as some that has recently been emptied of its stinky contents by ejaculating, but continuous dripping that SURROUNDS the meat is symptomatic of gonorrhea, and that meat ought to undergo inspection immediately while seeking medical attention.
　「Loose and dripping, stinky meat」also refers to thick-bodied, sluggish LARVA of certain insects. In particular, silk moth caterpillars with SCREWING, TWISTING motions within a cocoon built TO SURROUND themselves until metamorphosis, at which time the cocoon is EMPTIED. Refers to the SPINNERET of the caterpillar which spews a constant stream of wet, sticky, stinky silk from within its body meat out of an orifice at one end. Freshly-spewed silk is fairly stinky in fact. A single continuous fiber is used to construct each silk cocoon, averaging 1,000 meters in length (1,100 yards, 6/10 of a mile) wound in hundreds of thousands of「twisting, screwing」figure-eight shapes. The single fiber consist mainly of two fluids containing proteins: fibroin which is the odorless strong core used to make silk, and sericin which is the sticky, stinky glue-like substance that holds a cocoon together and is supposed to be washed away prior to spinning the fiber into thread.
　「Loose and dripping, stinky meat」equates to the silk caterpillar's spinneret as a male's PENILE MEATUS that spews semen ejaculate, also composed basically of two seminal fluids (sticky yellowish-white fluid containing the sperm, and clear mucus from the bulbourethral glands to provide lubrication through the urethra), and at times other emissions, while in screwing, twisting motions to empty its contents from a worm-like structure.
