[Elements vary by font and positioning] BODILY MOVEMENTS cannot occur without MEAT, also known as「muscle」which for most folks who ingest meat, refers to the muslces of the dead human or non-human animal that is being consumed. For full comprehension, be sure to see this glyph used as an element: ⺼, 夕, and 月 among others] meaning FLESH, MEAT, or a BODY PART:「We know that human sacrifice and cannibalism were widely practiced in pre-literate societies and that they were not local but universal cultural phenomena. …[T]he ancient Chinese also participated in this culture, which has much in common with the [Journal of Generative Anthropology] position about the violent origin and early development of human civilization…」

　「Human cannibals likely took a big bite out of their fellow humans about 10,000 years ago, according to a study that examined prehistoric bones with scratch and bite marks on them. …In the end, they discovered 30 bones belonging to three individuals: a robust adult, a gracile adult and an infant. However, the infant had only one complete bone (a shoulder blade, or scapula) that did not show signs of cannibalism, the researchers said. …But the practice goes way back: there's even evidence of Neanderthal cannibalism in Belgium and Spain from more than 40,000 years ago, when they went extinct, Live Science previously reported.」

　「Insides」of a「person」to a cannibal mean MEAT, and whether today we like it or not, all human societies in the past and other primates today remain cannibals.
　Most carnivores, such as vultures, lions, hyenas, and so on, when beginning to open a carcass to eat the available MEAT will start at the easiest and most tender point of entry, the groin located「between spread legs」by first tearing the anus, vagina, or scrotum wider, as the case may be.
　Topmost strokes are「enter, put into, insertion」between「spread legs」and inside that is a「person.」Primarily, the MEATY BODY PARTS that are being referred to are in fact the same as colloquial, vulgar references in the English of today to one's MEAT, with all the sexual innuendo of a person inserting meat into the meat of another.
　A「meat sacrifice」was the euphemism applied to a female giving up her normal life by having her feet no-longer-integrated and becoming「divine」as a hunk of meat and professional sexual services provider displayed in a「meat rack」of choices. In English also, people are often referred to as simply「bodies」such as with the terms some-body, every-body, any-body.
　When appearing as an element, this element is often written the same as「mooning」(⺼), a deliberate display of groin MEAT used by primates 'in heat' of estrus to attract mates for copulation by assuming a proceptive lordosis position. Some modern fonts use「person piled atop person」as the inner elements, indicating either MEAT SACRIFICES or ORGIES (or both) as seen in related glyphs (㫺, 齒, 俎). And finally, the glyph resembles a MEAT「rack of hanging persons」such as might be found in a cannibal's butcher shop, or a business establishment serving cheap liquor that offers pole dancing as entertainment: a meat rack of flaunting groins.
