Definition & Meaning of "fannyflaps"in English

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

"Fannyflaps" is a crude slang term for the labia or external folds of the female genitalia, likely emerging in informal English in the late 20th century. It combines "fanny," a common slang word for female genitals, with "flaps," emphasizing the physical appearance of folds, creating a vivid and vulgar metaphor. The term is used almost exclusively in sexualized, joking, or coarse contexts, often in pornography, crude humor, or informal conversation. It is highly derogatory and objectifying, never neutral or clinical.
