As an「orifice within a clusterfuck」please note that all sorts of non-human animals also engage in clusterfucking, although other animals do so generally as the means of species propogation.
　「Array of genitals, buttocks cracks in courtship display」clearly depicts a client-service provider relationship as being FOR HIRE, to EMPLOY the use of, contractual relationship for a short-term rental after making a selection. Upper-left element is「buttocks crack, door.」Right-lower element refers to a「bird displaying its plumage in a courtship display」and while on the ground.
　Referring to a species of bird that flaps its wings in a「door-like」manner with STIFF ACTIONS, the QUAIL, that nests on the ground in tall grass and seldom flies, but it must be admitted that quite a few bird species flap their wings a bit stiffly. Not too many bird species nest on the ground, but others do besides the QUAIL, yet elements resembling「bird under door」drawn in the same manner as human pit holes in the ground further identifies the QUAIL.
　STIFF ACTION applies to a NEWLY HIRED person who did not yet know how to do the job very well, that is, a person who works as well as a quail flies and keeps his or her head underground as much as possible. Probably also an oblique reference to the NEW HIRE as a cloaca「bird anus」since the multi-purpose aspect of that single organ being used for copulation, oviparity, and excretion may well describe the tasks assigned to and the feelings of a NEWLY-HIRED HUMAN BEING in the EMPLOY of a STIFF (the boss) and always taking it in the ass-end. And, as you probably have guessed by this time, elements as「buttocks crack courtship display」also uniquely identify this glyph with QUAIL. Of course, birds do not have a buttocks crack per se, but do have a cloaca, and among all birds it seems that only「The adult male Japanese quail has a well-developed cloacal gland that produces meringue-like white foam…and that males with larger cloacal gland areas are preferred during mating.」
　　[　https://www.publish.csiro.au/paper/RD11057.htm 2012-08-27　]　 ostensibly because of greater foam production during copulation…hmmm…and the feelings of a NEWLY-HIRED HUMAN BEING in the EMPLOY of a STIFF forcing a STIFFING ACTION, a person with buttocks crack filled with white foam who cannot fly off easily and spends all day in a hole in the ground, or, in a modern-day cubicle.
