Definition & Meaning of "capon"in English

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

Capon originally refers to a castrated rooster in English, a meaning going back to the Middle Ages. In gay slang, by the early–mid 20th century, it came to mean a young or inexperienced gay man, drawing on the rooster sense to suggest someone not yet "fully developed" sexually or socially. The term was mostly used within gay communities as a descriptive label rather than a severe insult, though it could carry a mildly patronizing tone. Today it is largely historical and rare, so using it outside of discussions of vintage gay slang may confuse people.
