There is an unwritten rule in the animal kingdom (recall that humans in fact are animals, and, that most animals cannot read so there is no point in writing down the rule) stating: nobody messes with the male having the biggest horn(s).「Spurting stance copulating in array of orifices」describes the ALPHA MALE of a harem, a CLAN CHIEF who rules the roost. Note that some fonts display the upper strokes as「on each side of, emitting down」rather than「emit up」(丷). Describes two items that are normally「emitted with a cock」as the BALLS, TESTICLES IN A SCROTUM, indicative of great CHUTZPAH, AUDACIOUS, IMPUDENT EFFRONTERY.「Cocky emissions」describes the BOSS, CLAN CHIEFTAIN, a COCK (or, a rooster) with his harem of hens and chicks. The guy drinking the hard stuff (pure alcohol is「emitted from a wine jar」as it evaporates).
　As「cock emits」the elements depict:「The rooster has a small phallus that becomes engorged with lymph to form a copulatory organ. The copulatory organ is rudimentary and at the time of mating there is practically no penetration. The hen everts her vagina during copulation [turns it inside out and outward], which helps to transfer the semen into the oviduct.」

　Roosters are quite proud of the little tiny penis that remains after hatching, one that starts out with much promise but then will「peter out」to a large degree (pun intended):「Scientists have now identified the gene responsible for eliminating or reducing the bird penis, which begins to form in the embryo but disappears again before the bird hatches. The critical gene, called Bmp4, directs cells at the tip of the penis to die faster than they grow back. In birds with elaborate equipment—not just ducks, but emus and ostriches as well—Bmp4 is switched off, letting their penises grow to full size…」
