In 2021, China`s National Radio and Television Administration added a ban on « sissy men and other abnormal aesthetics » to its rules using the offensive term niang pao.  People who call other Sissies are not only insulting the so-called Sissy. They also imply that there is something weak and fearful about being a girl or a woman – it`s the same as saying to a boy, « You throw like a girl. » This is unfriendly and also inaccurate. Sissy comes from her sister, and her first use for « female male » was in the late 1800s. In his book The « Sissy Boy Syndrome » and the Development of Homosexuality (1987), sexologist Richard Green compared two groups of boys: one group was conventionally male; The other group, whom Green called « female boys » and the other children « Sissy, » engaged in puppetry and other typical girl behaviors.  In his 15-year longitudinal study, Green examined sexual behavior in boys who later turned out to be transgender or homosexual, as well as a control group, and analyzed traits such as interest in sports, toy preferences, puppet fantasy, physical behavior (« act like a girl » versus rough play), cross-dressing and psychological behavior,: 21-29 with tests, questionnaires, interviews and follow-ups. He also studied the influence of parental relationships::353-369 and the response to atypical behavior. Subsequent follow-ups revealed that, in the end, 3/4 of the female or « sissy » boys became gay or bisexual men, while only one in the control group did. The analysis of the problem of nature and care has not been conclusive. :385 The word sissy in its original meaning of « sister » entered American English around 1840-1850 and acquired its pejorative meaning around 1885-1890; The verb sissifier appeared in 1900-1905.  In comparison, the word Tomboy is about three centuries older and dates from 1545-55.  The term sissyphobia refers to a negative cultural backlash against the « sissy boys » that prevailed in 1974.
 Sisyphobia has recently been used in some queer studies;  Other authors in the latter field have suggested effeminiphobia, feminophobia, femmephobia, or effemimania as alternative terms. Sissy (derived from sister), also Sissy baby, sissy boy, sissy man, sissy pants, etc., is a derogatory term for a boy or man who is not a man and shows possible signs of fragility. In general, Sissy involves a lack of courage, strength, athleticism, coordination, testosterone, male libido, and stoic calmness, all generally associated with masculinity and considered important to the male role in Western society. A man could also be considered a sissy because he is interested in typically feminine hobbies or profession (e.g., loves fashion), exhibits feminine behavior (e.g., uses hair products, moisturizes or shows sagging wrists), is not athletic or homosexual.  In the 1930s, « there was no more damning insult than being called a sisy, » and the word was widely used by American football coaches and sports journalists to denigrate rival teams and encourage wild play.  The use of the word sissy was « ubiquitous » among young American criminals in the 1930s; The term has been used to incite boys to join gangs, humiliate boys who violate group norms, enforce adherence to masculinity mandates, and justify violence (including sexual abuse) against younger, weaker children.  Good students have been ridiculed because the clothing and clothing styles associated with the upper social classes have been degraded as sissified. Among the members of a Detroit youth gang in 1938-39, Sissy was the « ultimate insult » used to tease and mock other boys as a justification for violence against rivals and as an excuse for not obeying the dictates of bourgeois decency and morality.
 In the late 1980s, some men began to recover the term sisy.  The alternative spelling cissy was used in British English at least before the mid-1970s.  In the United States, Comedy Central`s television series South Park reversed its meaning in a 2014 episode titled « The Cissy, » which mocked the controversy over the use of school restrooms by transgender students;  In the episode, a washroom originally intended for transgender students is later renamed « The Cissy Bathroom » for transphobic cisgender students. Sissy (third person singular simple present, present participle sissying, past simple and past participle sissied) Sissy is roughly the male opposite of tomboyish (a girl with masculine characteristics or interests), but carries more negative connotations. A study published in 2015 suggests that the terms are asymmetrical in their ability to stigmatize: Sissy is almost always pejorative and conveys greater heaviness, while the tomboyish rarely arouses as much concern but also creates pressure to adapt to social expectations.  In some communities, particularly those whose members are an integral part of Generation Z, strongly feminine men are referred to as « femboys, » a term that aims to provide a way to refer to female men without negative connotations.
