Meaning PULSATING, THROBBING that occurs with「changing rod states inside spread legs.」The element「two」is not exclusively representative of the count of two items, but rather can also be depicting two states, such as something that becomes wider and narrower or longer and shorter, the「one」element in both a widened and narrowed state, pulsating throbs within a set of「spread legs.」Of course, no one denies that「two at a time within spread legs」can result in feeling the PULSATING, THROBBING of all that meat (see 幵, 兩, and 姸 for examples). External sources suggest the meaning as SOMETHING COVERING A HEAD…without specifying which head.
　Perhaps the elements depict「two times within spread legs」as alternating between turgid and flaccid states, also known as a 'second coming' and what could be a divine, religious experience at times. In most cases, the「spread legs」element refers to either a human female, or, to the hind legs an animal of either sex…as an aside, this is likely due to early man equating the spread legs of a female human with the hind legs of an animal of either sex…see the glyph「sheep」(羊) for further details.
　Glyph may follow the pattern of other uses of「spread legs」as applied to a male animal in great distress from a prostate gland engorged with seminal fluid, perhaps sniffing pheromones wafting along on the breeze of a female of his species in estrus, causing the animal's penis to become erect and throb, pulsate, raise and lower a bit over and over and over again in anticipation of scoring and ejaculating, perhaps multiple times. Note that they don't call it「being in heat」for nothing. This behavioral condition is often evident with dogs, and the larger mammals such as bull moose and cattle, bear and swine boars, stallions, elephants, rhinoceroses, walruses, gorillas and other primates, but normally excluding bonobos and human beings who have full use of one hand or the other in order to provide instant relief as needed. Refers to dogs somewhat rarely, since most dogs have the divinely-given ability to self-fellate, or for those more scientifically minded, dogs evolved this wonderful talent through the miracle of natural selection (…so, how else can you explain that ability? one way or the other, dogs do it).
