Much like the Cleveland Steamer, this act involves depositing fecal matter on another human being. The direct act of San Dusky Soft Serve is as follows: You want to break up with somebody, you wait till they're asleep. Then, you open their mouth and take a nice ice cream soft serve type shit right in it. Punch them in the head to wake them up then flee the scene.
Jimmy hated Miss.Bojingles, so he decided to leave her with a Sandusky Soft-Serve as a parting gift.
