Slang terms for vaginal flatulence include queef,[2][3] vart, and fanny fart (mostly British).
[1] Vaginal gas with a strong odor of fecal matter may be a result of rectovaginal fistula, a serious condition involving a tear between the vagina and colon, which can result from surgery, childbirth, diseases (such as Crohn's disease), or other causes.
Vaginal gas can also be a symptom of an internal pelvic organ prolapse,[7] a condition most often caused by childbirth.
[8] Puffs or small amounts of air passed into the vaginal canal during cunnilingus are not known to cause any issues.
However, "forcing" or purposely blowing air at force into the vaginal canal can cause an air embolism, which in very rare cases can be dangerous for the woman, and if pregnant, for the fetus.
