Getting a blowjob on the toilet while taking a dump. Actually making sense compared to such random terms as the blowken. This act represents a girl at an icecream shop pulling a handle and letting the soft serve ice cream fill a cone or bowl.
"Debby went down on Tony while he was taking a shit. It was the best soft service hes ever had, and she loves the smell of crap."
