TOO EARLY as it relates to timing, and referring to velocity.「Tonguing mouth screwing」or「rod at dawn.」Recall that until the last century or so, young female children in China were legally sold for just this very purpose (see 㔬), and were obviously therefore purchased for this same purpose, with those who were well-trained and experienced able to fetch the highest prices.
　Suggested as a simplified replacement of the old glyph「get naked with tonguing mouth」(曩) that bonobo-like human beings performed in the early morning when most males were erect (see 夢 for a more detailed explanation of morning erections). Chinese meanings indicate something dropping「down vertically from a tonguing mouth」as in COMING BEFORE OTHERS, then experiencing a flaccid state. Modern version of「tongue in mouth on the verge」or「twisting, full, screwing」may have indicated HASTINESS of an EARLY ejaculation (see the vocabulary lists and related glyphs). Also meaning a PROMPT, to「receive a cue from someone else for when to quickly react.」…as in the depicted elements, reacting to avoid being struck in the eye, hair, or gagging on the discharge (晻), and so on.
　「Sun」and「perfectly full」may suggest to some folks that the Sun has risen, but it ought to be pointed out that the Sun will appear to remain perfectly full all day until sunset and therefore「perfectly full sun」does not apply only to the dawn, often depicted incongruously with the Sun halfway above the horizon, not full but half obscured by the Earth itself…elements maybe describe noon on a cloudless day, though. Furthermore, this set of elements does little to explain the meanings of premature, prior to maturity, fast, prompt, or early arrival, considering that the Earth rotates at approximately the same speed throughout the day, and most nights, too. Note that the Sun does not actually rise, traverse around the Earth, and then set as many humans believed and taught until fairly recently, torturing to death those who disagreed. However,「day full screwing」「female role tonguing on rod」may describe the schedule of a PRECOCIOUS young service provider who must start the workday EARLY (upon awaking, at any time of the day or early night) with the breakfast of champions, a series of nourishing, steroid-laden, fructose-filled cocktails…or so the sages observed.
