Slippery Steve 

When, while taking a dump, one allows a turd to partially leave the ass, and then pulls it back into and out of their asshole repeatedly. Also called "shit fucking".

Rob: "What took you so long in the bathroom?"

Steve: "I was giving myself a Slippery Steve."

Rob: "That's.... terrible."
