Get the Queefmug. Air expelled from the vagina, sometimes mistaken from a fart. Air is sucked into the vaginal opening when a foreign objectt is pushed in from a certain angle creating a vacumm. The release of air causes a farting noise. Queefs are common during sexual intercourse (especially the acrobatic kind) and even after if air is still trapped.
