Definition & Meaning of "bog queen"in English

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

Bog queen is British slang that emerged in the mid–late 20th century, mainly within urban gay communities. Bog is informal British English for a toilet, and queen was common in gay slang as a labeling or stereotyping term, often with a sharp or mocking edge. The phrase refers to someone who frequents public toilets seeking anonymous sexual encounters, especially during periods when few other meeting places were safe or available. Although it describes a specific behavior, it often carried a dismissive or derisive tone, even within the community, implying secrecy, low status, or poor discretion. Today it is largely historical and offensive, and is mostly encountered in discussions of past slang or social conditions rather than everyday use.
