The place for「simplest emissions」and the「fruits, effect, results of stuff spewing」is within one's own home NEST or BURROW, DEN (be sure to see the Chinese version, 巢).「Dazzling, flashing, and stuff flying out」with「results, effect of woody plugging, screwing an orifice.」…not all nests are found in trees, by any means, as many are burrowed into soil: see 窠. Nevertheless,「stuff flying out but not yet in orifice of muck slurry」suggests that the natural orifice containing gametes is engaged, the only method in the old days for successfully BREEDING.
　「Plugging orifices in rotation with downward emissions」suggests a parent bird vomit-feeding a NEST of chicks vying for regurgitus in a rotation to keep all fed with similar amounts, with all the chicks resembling Medusa's hair of vipers and hoping to receive a「filled mouth orifice.」
　「Pronged heads, defense, fasten, detain」with「tree, wood」also applies to some NEST types. Old glyphs use「tongue in mouth」with「loose, unbounded」with「tree」perhaps to depict many birds chirping in a NEST and those little birdies all together with gaping mouths do look a bit like a single animal having one「pronged head」i.e., a gaggle of hungry pre-fledgelings.
　Regardless of the original elements or its location within trees or soil, a NEST also serves as a place of「defense」for「detaining」one's young until mature enough to fend for themselves.「Plugging dazzling orifices in rotation with downward emissions」also leads to BREEDING PLACE, HIVE, DEN as the shaman's quarters for training small, young apprentice concubines held for trade, sale and resale, as「billing form for emissions」or「dazzling spurting woody plugging, screwing in orifice.」No one can deny that「simplest emissions」are with young'uns next to an adult in a den or while nesting…for bonobos, humans, and many other species:「In traditional Chinese medicine, there has never been a mental disease called pedophilia (or an equivalent term), or homosexuality, or most of the other so-called sexual variations for that matter. …Children are usually described as natural sexual beings and erotic stimulation and sex-play are seen as beneficial to their healthy development.」

　「Like humans but unlike chimps and most other animals, bonobos separate sex from reproduction. They seem to treat sex as a pleasurable activity, and they rely on it as a sort of social glue, to make or break all sorts of relationships. 'Ancestral humans behaved like this,' proposes Frans de Waal, an ethologist at the Yerkes Regional Primate Research Center at Emory University. 'Later, when we developed the family system, the use of sex for this sort of purpose became more limited, mainly occurring within families [i.e., incest]. A lot of the things we see, like pedophilia and homosexuality, may be leftovers that some now consider unacceptable in our particular society.' 」
