Femminielli or femmenielli (singular femminiello, cf. Standard Italian femmina, "a female," -ello, masculine diminutive suffix) is a term used to refer to a population of homosexual males with markedly feminine gender expression in traditional Neapolitan culture. It may be hard to define this term within modern Western notions of "gay men" versus "trans women" since both these categories overlap to a degree in the case of femminielli (see: Third gender.) It has been noted that this term is not derogatory and does not carry stigma, instead femminielli are traditionally believed to bring luck. Ironically Achille della Ragione suggests that recent surveys have shown that Neapolitans have a generally negative view of what he calls "the politically correct model of homosexuality of a hypocritical do-gooder society" (implying the mainstream Western gay culture), yet he contrasts femminielli as enjoying a favorable attitude from the part of Neapolitan society.
It is reductive to insert the Neapolitan Femminiello within the macro-category of transgender or transsexual, usually adopted in Anglo-Saxon and North American contexts. The femminiello, instead, could be considered as a peculiar gender expression, despite a widespread sexual binarism. The cultural roots of this phenomenon are embedded in confer to the femminiello a cultural and even socially legitimized status. For the historical and symbolic coordinates of Naples, the identity construct of the femminiello is not superimposable to more common European and euro-centric transgender clusters.
In late 2000s many sex scandals have rocked Italy involving high-profile politicians (e.g., former President of Lazio, Piero Marrazzo) and transsexual sex workers often of Latin American descent, who are usually referred to as transessuali (shortened to trans) in Italian media. In 2009 the term femminiello gained some notoriety in Italian media after a Naples native femminiello Camorra mobster Ketty Gabriele (legal name Ugo Gabriele) was arrested. Gabriele had engaged in prostitution prior to becoming a capo. Gabriele has been referred to both as a femminiello and transessuale or trans in Italian media.
