Definition & Meaning of "effie"in English

What is the origin of the term "effie" and how is it used?

Effie is a slang term that appeared in early–mid 20th-century English to describe an effeminate man. The word is a shortened form of "effeminate", used as a nickname or label for men perceived as delicate, soft, or feminine in manner or appearance. Historically, it was derogatory, often employed to mock or belittle men who did not conform to traditional masculine norms. Today it is largely historical and considered offensive, and using it outside discussions of vintage gay slang is likely to insult.
