That phenomenon when you're about do go down on a chick, but you don't know how much jizz is left after raw-dogging, so you send an exploratory finger down there. Just like sending down a canary in a coal mine to test for a hazardous cavern.
This chick wanted me to head downtown, but I thought there might still be a salty surprise left over from earlier, so I sent down the canary to make sure the coast was clear.
