Queef
From Wikipedia, the free encyclopedia.

A queef is the slang term for an emission of air from the vagina, often during or after sexual activity. The sound is somewhat comparable to flatulence from the anus, hence the nickname "fanny fart". The sound is most often associated with air expelled during or after vaginal intercourse but can also happen during cunnilingus or anal sex.

The occurrence after intercourse appears to be due to the decrease in the size of the vagina as it returns to a quiescent state when arousal ends.

If this is undesirable, the chances of this occurring can be minimized: for vaginal intercourse, the outward pushing Kegel exercise can reduce the chance of it happening, as well as avoidance of sexual positions where the woman raises her hips and thighs (such as when raising the legs over the head, which helps to form a tight seal during the inward strokes.)

Queefing can also be considered erotic, and is the subject of a pornographic sub-genre.
