「Bowing over on all fours with squeezing and shaking grip」: depicting the position or posture used while GAMBLING, that being a group down on hands and knees in a circle surrounding the cash or gambling tokens, and shaking dice or other implements used in a game of chance. Scholars say this is apparently a small「bamboo」device used both as a gambling CHIP, or a TOKEN substituted for cash while playing and for counting the score. Alternatively, as「bamboo two-handed masturbation」GAMBLING TOKENS in a squeezing grip may contain a commentary of the virtues, or lack thereof, of gambling as a means of killing time.
Or: elements as「down in a proceptive lordosis position offering one's spread buttocks with erection prick and feel of fluids pumping in a squeezing grip」kowtowing (bowing over as does「bamboo」) as an offer to any passerby with some loose change, selling short-term access to one's redeye in order TO RAISE FUNDS whilst ASSUMING GREAT RISK as a MEANS TO AN END, a RESOURCE used to enhance one's begging in order to stave off starvation for another day in dynastic China.
Furthermore, per some dubious sources, GAMBLING CHIPS were also used to wipe residual feces with a squeezing grip from one's bunghole after defecating or prior to the next passerby with loose change, with the smoothly finished surface of the oldest and worn chips providing the most satisfactory results without nicks and scratches…which also explains why GAMBLING CHIPS were so named.「Bamboo with a lifelong activity」which is to say that no one likes to play with sticky chips. Perhaps the origin of the expression「dirty money」(why throw the chips away?). Rumored as the source for the invention of flavor-enhanced, salty「finger foods」while playing board and card games. Insufficient hard data exists to establish any link with a「chips and dip」theme, but one can imagine the various sorts of material clinging to a soiled chip token after use. Perhaps the source of the English expression,「that's the ticket!.」
