「Loosely pulled out of shape」that euphemistically was defined as a the SNOUT OF A SWINE, or SNOUT OF A DOG by prior lexicographers, perhaps due to its resemblance to two long nasal cavities, or also likely as a clever allusion to due to the swine's ability unique among animals to burrow deeply into soil using only the snout, similar to the human male penis when erect, and a dog's affinity for sniffing anal orifices: both boar and dog SNOUTS are euphemistic of a human male's erection: long and hard with an orifice at the tip: swine use their snout to burrow into soil seeking mushrooms (imagine that) and dogs poke their nose into an anus in order to identify the scent of the anus' owner for later reference. Other analogies remain fundamentally for the reader's fertile imagination of fundaments.
　「Biting, clenching one's teeth, chewed」inside「pulled out of the normal shape to one side」describes an extremely painful procedure causing the sufferer to「clench teeth while flesh is being pulled to one side misshapen」bougie reaming to chew up the inside of a urethra, performed on a sensitive body part known euphemistically in ancient China as a PIG'S SNOUT, likely due to its ability unique among animals to burrow deeply into soil using only the snout, similar to the human male penis when erect. Glyph might have something to do with the English,「keeping one's nose clean」in various respects. In addition, all known species possessing fingers use them to「ream the orifices of the snout」in order to root out boogers of dried mucus discharge that are often green in color, with the finger acting as does a bougie.
　Element depicting a PIG SNOUT. Perhaps a vertical「biting fang」(レ) of a wild boar merged beside the pig's snout element (彐), teeth clenching and pulling at flesh. As omnivores, wild boars eat most anything and primarily vegetation, but also scavenge carcasses left by other predators, or devour smaller prey while still alive and if it will fit into its mouth, not bothering to kill prey if it is otherwise incapacitated, often resulting in the boar's snout becoming covered with the victim's bodily fluids and blood. Pigs eat feces, too, when they can get it.
　「The snout of the Wild Boar is probably one of this animal's most characteristic features, and like other Wild Pigs, it sets these mammals apart from the others. The snout of the Wild Boar has a cartilaginous disk at the end, which is supported by a small bone called the prenasal, that allows the Wild Boar's snout to be used as a bulldozer when it is foraging for food. All Wild Boars have tusks on their bottom lips, although the male's are larger than those of the female, and actually curve upwards out of their mouths. More interestingly however, males also have a hollow tusk on their top lip too…」

　「It would be shorter to list what hogs do not eat than what they do eat. They are omnivores (eating both plants and animals) and opportunists, and will eat virtually every plant or animal available. They are not generally thought of as predators, but they are. They are drawn to birthing areas by their acute sense of smell, and will eat the newborn and placenta so there is no trace left. Ranchers cannot tell whether they lost newborn stock or never had it. They prey on reptiles (including rattlesnakes), amphibians, birds and their eggs, insects, worms, and any smaller mammal, dead or alive, that makes itself available. Carrion is eaten with relish, and hogs are known to eat manure. Favored vegetation is acorns, any fruits, seeds or nuts, mushrooms, roots, bark, and although they are not grazers, they will eat some grasses.」
