Perhaps these elements are「raw meat under Sun」after a「victory, be better than」as a defeated opponent who lays bleeding or dead with meat exposed, exuding a FISHY ODOR OF BLOOD AND DEATH to mean RAW MEAT, RANK, STINKING, STRONG-SMELLING.
As the「Moon and star(s)」often insisted upon by scholars and artificially intelligent software agents, the elements quite obliquely suggest doing something sneaky, SUSPICIOUS under the cover of night and darkness (not the bright light of the Sun) as FISHY activity, but not yet exuding much odor, necessarily. Granted, this interpretation requires a huge inductive leap of your logic, and might be considered to be only another goofy mnemonic as it fails utterly to describe RAW MEAT, RANK, STINKING, or STRONG-SMELLING, until you also consider the additional meaning of a CORRUPT RELIGIOUS FIGURE by recalling that the elements on both sides are situated in the environment of heaven, not coincidentally the claimed source of authority by religions generally.
In its original parlance, describing a thing or situation as "smells fishy" did refer to having probable cause for extreme doubt and suspicion, but most folks do not realize why innocuous fish are so maligned in this manner. A fishy or pungent-smelling discharge from the vagina and/or penis may signify the presence of an infection, so caution was advised...and still is today. Elements as the 「meat of a star (well-known service provider)」or as the「meat of a prick head below a tonguing mouth」covers both parties to any short-term rental or other experience of sexual services. FISHY ODOR, DUBIOUS, SUSPECT DANGER comes from「raw prick head meat」with a「tonguing mouth」as the two body parts approach one another in close proximity, or for some, even from fairly far away. The FISH, FISHY ODOR meaning also derives from the「meat of a star」sexual performer in the shaman's cave o' wonders, shrine of divas, temple of love:
「Trichomoniasis (commonly referred to as 'trich') is the most common, curable sexually transmitted disease in the world. …Trichomoniasis is caused by a one-celled parasite, Trichomonas vaginalis. Trichomoniasis affects both women and men. The most common location of infection in women is the vagina, and in men it is the urethra. In women, the symptoms of trichomoniasis may include yellow-green vaginal discharge, fishy odor, pain during urination and sexual intercourse, and genital itching or irritation. Men usually do not show trichomoniasis symptoms, but some may experience discharge from the penis or burning during urination or ejaculation.」
