A moist expulsion of air from the vagina, best seen on colder days.
"You can tell it is cold out when, your see a women and she has steam coming from her vagina region, you know she just let out a good steamy queef...."
The end result of when you are done penetrating a female partner with a non-finished bottle of red wine. Usually it's a 'fart-like' sound emanating from the vagina, spraying wine all over the bed. Using a bottle of white wine would result in a 'Pinot Grigio Huffer'.
Jenny is the wine queef queen! She soaked my bed in red, and it looked like a murder scene!
A pre-queef is, in all literal thought, the conceptual pretext to a queef. As in a pre-fart of the vagina. A queef itself is just full-on air being released from the vagina in a flatulence sounding manner. It's like the formation of a queef.
On the other hand its also defined to be calling someone a pre-queef, as saying they are no better than even before the magical glory that is inserting air into the vagina to be released as a fart sound, usually half the time just as bad of a smell, yet from something you strive to put your penis into every moment.
