1. A sex fart; also known as the sound a vagina makes when air is forced inside, but promptly displaced by another object
2. The resulting sound of two solid, lubricated surfaces suctioning away from one another (as in intercourse when sweat covers two opposing body parts and contact between the two has momentarily subsided)
