When a sexual partner is standing vertically, spreading the legs 30 degrees apart, at which point an aerosol can of whipped cream is inserted anally. The trigger is pressed, opening the can and forcing mostly CO2 and some cream into the stool. After 10-20 seconds, a sensation in the lower bowels occur, signaling the partner on the receiving end of the insertion to release the compressed gasses and byproducts onto the other partner's face, or dessert of choice that will be consumed by the opposite partner.
