Definitions by Ericsegall

A colloquial, somewhat crude term for the vagina, specifically referring to the external genital area formed by the labia majora and labia minora.
The phrase plays on the visual imagery of "flaps" (the labial folds) and the natural "gap" or opening between them. It's typically used in casual, irreverent, or locker-room-style conversation as a playful or vulgar euphemism.
Example usage:
"After that long hike, Margaret's flap gaps were sweatier than expected."

"Bill is obsessed with getting up close and personal with joan's flap gaps."
