Definition & Meaning of "water-lily"in English

What is the origin of the term "water-lily" and how is it used?

Water-lily is a slang term that emerged in early–mid 20th-century English to describe a gay man with particularly feminine traits, appearance, or mannerisms. Like other floral metaphors such as tulip or daisy, it draws on the delicate, graceful qualities of the water-lily to highlight softness or refinement. Historically, it could be used playfully within gay communities or mockingly by outsiders. Today, it is mostly historical and uncommon, and using it outside informed or affectionate queer contexts may feel patronizing or outdated.
