「Cocks, wine jar」with「bonobo-style clusterfuck」: the first religion was shamanism, the practice and belief of glorifying sex. In actual practice, most humans still glorify sex. It is possible, but unlikely, that much good wine (or even cheap wine) will be poured out onto the ground for any reason whatsoever, let alone by the adherents of a religion that glorified hedonism during a carnival (maybe, a little wine was spilled, or the offering amount was tiny). English word 'carnival' literally means「meat is raised, lifted.」…various type of meat, rods raised or buttocks in lordosis position.
　「Cock juice」when「connecting, hooking up in many crotches」more likely would have been pumped into [night] soil, especially as part of a religious festival such as the traditional shamanist rites of spring. As an aside, the dogmas of present-day mainstream religions that instill fear of eternal punishment or loss of eternal bliss as the consequence of sin were intended to cause humans to cease destructive sexual habits that spread infection epidemically, such as what is depicted by this glyph, and for very good reasons.
　「Wine in many crotches」: or, the glyph is depicting the prevalent use of wine used initially as a bacterial-killing douche or treatment for anal gonorrhea, a DISINFECTANT, that also caused some euphoria, today accomplished for the purpose of getting high by inserting a vodka-soaked tampon into the vagina. Literally pouring alcohol directly into rectums was not uncommon and more economical when used among a group of members or buddies, such as army squads, since far less is needed to enable the effects:「An alcohol enema, colloquially known as butt-chugging, is the act of introducing alcohol into the rectum and colon via the anus. This method of alcohol consumption is dangerous because it leads to faster intoxication since the alcohol is absorbed directly into the bloodstream and neutralizes the body's ability to reject the toxin by vomiting. …An alcohol enema is a faster method of alcohol intoxication since the alcohol is absorbed directly into the bloodstream. The lower gastrointestinal tract lacks the alcohol dehydrogenase enzyme present in the stomach and liver that breaks down ethanol to make it less toxic for the body. …Additionally, consuming the alcohol rectally neutralizes the body's ability to reject the toxin by vomiting. Overall, experts believe that alcohol enemas are a dangerous method to consume alcohol.」

　The real question is, how did the ancient Chinese discover this effect in the first place? perhaps while treating a vaginal or anal infection of gonorrhea. Moreover, the subsequently very loose stool saturated with wine near the rectum and complete inebriation of the group likely elicited subsequent「cocks and bonobo-style clusterfucking」among buddies, too. And, now you know why many wine, beer, and distilled spirits bottles have such long necks.
