What is "vaginal flatulence"

n. (context slang mildly vulgar English) A noisy emission or expulsion of air from the vagina.

Vaginal flatulence is an emission or expulsion of air from the vagina. It may occur during or after sexual intercourse or during other sexual acts, stretching or exercise. The sound is somewhat comparable to flatulence from the anus but does not involve waste gases and thus often does not have a specific odor associated. Slang terms for vaginal flatulence include vart, queef and fanny fart (mostly British).
