Reminiscent of a wife of Old Lodge Skins named「Doesn't Like Horses」…but of course, she's lying. Note the given meaning of UNFILIAL that seems to mean not respecting one's parents and their teachings (aren't young female horses also called「fillies」in English?), but may also relate to a masturbating female horse: these elements after all are「deep feeling stream of emissions, young and small with a horse, horsing around with dildo plunging joysticks」(see 馬). Filial simply means having or assuming the relationship of a child to a parent, and「filly」in English also refers to a lively, high-spirited young girl「concerned with head sliding.」…but this may be purely a semantic coincidence. Yet, putting all that together with the many other glyphs that refer to father-daughter relations, this one intimates that she prefers her selfies rather than her close male relative(s), and is STUBBORN about it, understandably. The parents are then「concerned about her head sliding」as another rendition of the elements. INSUBORDINATE means not behaving in submission to those in a higher social position, being rebellious and not conforming to the established rules of order.
「In traditional Chinese medicine, there has never been a mental disease called pedophilia (or an equivalent term), or homosexuality, or most of the other so-called sexual variations for that matter. …Children are usually described as natural sexual beings and erotic stimulation and sex-play are seen as beneficial to their healthy development.」

「Like humans but unlike chimps and most other animals, bonobos separate sex from reproduction. They seem to treat sex as a pleasurable activity, and they rely on it as a sort of social glue, to make or break all sorts of relationships. 'Ancestral humans behaved like this,' proposes Frans de Waal, an ethologist at the Yerkes Regional Primate Research Center at Emory University. 'Later, when we developed the family system, the use of sex for this sort of purpose became more limited, mainly occurring within families [i.e., incest]. A lot of the things we see, like pedophilia and homosexuality, may be leftovers that some now consider unacceptable in our particular society.' 」
