queef (kweef) n.
the expulsion of air from a vagina after sexual intercourse, usually very fast-paced or deep intercourse, and most often resulting after the "doggy style" position, or variants of said position. queefs are known to have a "wet" sound, and can occur during intercourse, or after. queefs occur when an object, usually a penis, creates a vacuum of air inside the vagina, usually because of a certain angle or position, or because of use of a condom, and happen when the penis or object is removed or pushed deeper into the vagina. many think of queefs as a "sex interrupter" because females are usually embarrassed and males usually embarrassed or amused as the very unique and recognizable sound of a queef.
