Formerly perhaps a LONG-SNOUTED PIG, later used as a reference to both HEDGEHOGS and PORCUPINES, neither of which are actually pigs and instead are rodents, but both still contain「hog」or「pork」in the name due to some vague resemblance of their snouts (in English, also) it is assumed. Both hedgehogs and porcupines are endowed with stiff quills for protection, although the porcupine's are far more debilitating than the hedgehog's. The porcupine NEVER FLEES FROM AN ATTACKER, instead rolling its body into a defensive ball and presenting sharp, detachable quills in all directions. While a predator may get to take a snap or two at first, the quills embedded deeply in its mouth prevent much further interest in dining on the porcupine, as well as prevent the attacking animal from being able to simply close its jaw, resulting in a successful defensive strategy. In this manner, a porcupine will defeat even a tiger.
The image of a quill reaming one's long pig snout with the patient standing up to the pain and not fleeing enables the medical practitioner to provide a PROGNOSIS, foretelling the future need for continued bougie-reaming sessions or DIVINATION, the various services of knowing the will of the gods (religion) for a patient, prostitution, and doctoring offered by shamans. Also derives from these elements as「obese piggish concubine/ service provider with pig nose in need of bougie reaming」that can describe the shaman as witch and doctor providing medical services with a long quill-like object or an actual porcupine quill, and, to the worker not shirking her DIVINATION duties even though a client is obviously diseased, rolling a no-longer-integrated foot into the necessary shape and NOT FLEEING FROM AN ATTACKER, remaining UNINHIBITED and FEARLESS knowing that cleansing salts are available afterward. Perhaps the porcupine received its English name from the use of its quills as bougie reamers of pig snouts in China, piggish meat mingled with needles, erectile bristles.
