When the penis leaves thee vigina to quickly or hardly it often makes a air socket, hence making qeef while leaving the vigina. Also could be considered a vigina fart.

When, after an extended episode of concentrated reasoning, a lady realises that she has discovered a hitherto overlooked flaw in Einstein's Relativity Theory but coherent speech is made an impossibility due to an intense level of sexual excitement, she must resort to an audible vaginal emission to convey her profundities to any fortunate peer within earshot. The pungency of the resultant qeef can be overpowering and is directly proportional to the originality and validity of the lady's deductions.

Lady, ditto: "That, Archibald, was a post-structuralist analysis of the novel Bleak House by Charles Dickens."
Man: "It friggin' stinks!"
