「Bent and dripping short leg with stench cloud」above「orifice.」It is noteworthy that the original form also included the element meaning「short hairs, fur pelt, pubic hair」(㣍). Scholars say UPON A PLATFORM, waiting and watching for a mudflow, landslide, tsunami, typhoon, tidal surge, huge discharge, or flood waters, explaining that this glyph depicted a base built to be higher (㙵) than the previously known high-water flood level, with revised elements of「getting lucky, bound on all sides to the extreme」(臺) but simplified to depict「stinky short leg and orifice」due to boredom, killing time, nothing else to do, getting horny, or becoming really good buddies up there alone all that time.
　A raised STAGE or PLATFORM as a heavy BASE would hopefully not be swept away by floodwaters or severe winds. A few soldier guys on a secure platform from which to watch for an approaching river flood during and soon after heavy regional rains or a typhoon…perhaps it was, but the original glyph elements depict a raised stage or platform upon which a large audience on all sides could witness those few guys engaging in various forms of engagement, with everyone watching and waiting for the huge discharges…remember at that time and place, homosexuality was common, homosexual love was highly regarded, and everybody cheered when one soldier's discharge catapulted his buddy across the STAGE, PLATFORM. Used as a raised BASE for mounting various war MACHINES with「loose arms that appear as if dripping a long thread, and then flinging chunks」such as CATAPULTS. Note this is likely the source of the English word 'dais,' and the described actions uncannily resemble the ritualistic motions of sumō wrestling performed on a raised staging area.
