Describes using hands to PULL UP, or PULL OUT, or the sound made when EXTRACTING a cork from a wine bottle. Formerly,「talented hand use」and「one's dog, hand emphasized on crotch」(original Chinese version: 拔), WHIP IT OUT. Meaning to DISENGAGE, to PLUCK or A PULLOUT. Anyone who has ever lived with a dog knows canines do not have hands. Anyone who has ever lived in the woods with a dog will know this glyph might suggest helping the animal by pulling off the blood-sucking ticks that gather around its head, back, and neck (most other places on its body the dog can take care of by itself). And most certainly a reference to lending assistance to animals attempting to disengage a penis and bulbus glandis from a tightly constricted vagina after ejaculation during copulation (that sucking sound perhaps, as listed in original Chinese).
　Japanese element changed from「dog」to「friend」(man's best friend, naturally). Maybe as monkeys do, humans「using hands on a friend」to help them groom themselves by plucking out hard to reach hairs, ticks and lice (if they have them), removing pimples or enemy arrows from their back, grabbing them by the back of the neck or collar and plucking them from danger or when they are standing in the wrong line for concert tickets, or when it is time to flee from approaching authority figures, and so on.
　Male canids, the 'dogs,' are endowed with a very special penis, unlike any other species. A dog is equipped with two glands located at the base of the shaft that engorge and harden upon erection, normally after baculum penetration into the bitch's vaginal orifice (a baculum is a bone located within the dog's penis that enables rapid insertion, i.e., spearing). These locking bulbus glandis swell large enough to prevent the penis from being extracted from the bitch's vagina for quite some time, normally ten to fifteen minutes (or up to an hour in some cases), to allow the dog's semen sufficient time to get enough of a head start toward the bitch's ova that the male might actually sire some pups, completing his mission in life, rather than the next dog waiting to mount the same bitch in heat. Sometimes, assistance is provided when DISENGAGING the male and female canids,「talented use of hands with hand in crotch.」
