When one rings up the elevator to the fourth floor, waits for the door to open and then proceeds to blow ass into the elevator, at which time the lobby button is pressed, sending the ass cloud, by itself, down to the individual(s) waiting to get on the elevator.
The big man was less than pleased, when after waitng for the elevator for over 5 minutes, he was met by the usual culprit's game of Send it Down from the 4th floor

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.
