It's the built up air present in a ladies vagina after she has had a night of long hard sex. The sweet air is expelled through the vaginal crevice causing her pussy lips to flap back and forth at top speeds making a sloppy fart sound.
Hey did you hear Lisa droppin those poonie farts last night in her sleep? They sounded sloppy wet and nasty. Hope she had her panties lined up right.
