The beautiful act of inserting a Cadburys egg (Or another well known brand) of whichever proportion seems suitable for the size of said oriface (anus) or how hungry the rimmer is. After waiting for 3 to 5 minutes for the chocolate to become more fluid in consistency the rimmer can proceed to clear the area with their tongue until satisfied that no secretions are left to mark the sheets or sofa or park bench or swimmingpool (Exteme caution is advised when underwater rimming) Rinse and repeat until both rimmer and reimmie are satisfied they are comfortably full.
