Given a man whose package I didn't have any interest in, I might sweetly say, "Darling if you continue to anger me, there will be a swift blow to your cohonas."
If my intent was to ensure my toe hit destination scrotumville my "warning" would be very cryptic... something along the lines of, "is that a stain on the ceiling?" or "Hey, is that a star or a UFO?"... something to divert their attention from my business foot.
