The secreations emitted from either male or female genitalia. Meaning the fluid from the genitals, when leaked or "spit" from said penis or vagina, can the be refered to as genital spits. IE: The white spots on your dark sheets....that your mom saw the other day, and started sweating you about. But you told her it was a milkshake, shame on you.
Me and my girlfriend got so hot and heavy in my car last night, we got our genital spits all over my backseat, and the passenger seat, the driver's seat, the sterring wheel, and just a couple of spots in the trunk.
