「Noticeable on/with pubic hair」and an association with SHAGGY DOG, HUGE VOLUME TREMENDOUS DISCHARGE. Also meaning A MESS OF, MESSY, and it is noteworthy that some pundit scholars suggest that this glyph was modified and used as the right-side element of「dragon」(龍), the glyph corresponding to the Dragon Emperor of dynastic China, who indeed maintained A HUGE MESS of females in his harem for SHAGGING, that is to say a large CLUSTER OF FUR PELTS (also known colloquially as「beavers」).
　JUTTING IN MANY DIFFERENT DIRECTIONS stemming from「erect rod and penile hairs with emphasis」should need no further explanations.
　HUGE DISCHARGE: during ovulation of a female human and estrus of other animals, the individual can become more sexually aroused than at any other time.

　「Noticeable pubic hair」is UNKEMPT. The「hair of one's dog」and naturally THE DOG itself.
　SHAG is coarse nap in a tangled mass as seen on goat and sheep fleece, and not coincidently, in Britain SHAGGING means「engaging in sexual intercourse with something」such as by firmly grasping ewe by her hind shag and sheep-tupping, or by using one's own hand as in what is handy. Highly noticeable. Different colors and stripes in all directions. Being a jerk in public, jerking publicly with ewe, and so on. Perhaps the source of the English colloquialism「hair of the dog」as an unkempt, messy, hungover person in need of some pain killer…alcohol was used as an anesthetic, but its use as such was generally discontinued due to the toxic effects of overdosing.
