「Moist infection with sticky splat」or「juices with raised rod, divine orifice and emissions in all directions」need no explanation.
　「Fluid surrounding the brains in the skull that is salty」is cerebrospinal fluid. The same liquid is used as GRAVY to cover a meal of raw brains. The same type of juices and liquefied fat that oozes from cooking chunks of dead animal tissue, used to baste the meat, and then mixed with a little salt and a thickening agent, perhaps a pat of butter and a little milk or cream is also nice, to be ladled over the flesh prior to human consumption.「Flow of stupidity」relates to eating undercooked brains, the source of kuru…brain fluid is very salty, since sodium ions are essential to enable electrical impulses to pass between synapses within the brain, but too much salty juice also can cause a heart attack, and cave folks probably found out the hard way, in addition to contracting kuru:「Kuru is found among people…who practiced a form of cannibalism in which they ate the brains of dead people…. Kuru causes brain and nervous system changes similar to Creutzfeldt-Jakob disease. Similar diseases appear in cows as bovine spongiform encephalopathy (BSE), also called mad cow disease. The main risk factor for kuru is eating human brain tissue, which can contain the infectious particles. …Death usually occurs within 1 year after the first sign of symptoms.」

　It is no coincidence that the English root word「broth」meaning fluids in which meat has been heated, cooked and fired, is used to describe「someone who broths」as a brother and a「house for brothing」as a brothel. Concubines used salts in the deep skin slits of their bound feet to accomplish two things at once: dry the skin, and disinfect any wounds or straggling bacteria left by clients.
　「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.」
