This is an oral sexual act preformed on a male during cold-weather periods due to the enhanced feeling of warmth that pervades after administration. To perform, first smother the scrotum and lower base of the penile tissue with Cheese Whiz. Next, allow the consuming partner to satiate themselves by vigorously consuming said Cheese Whiz in any way the receiving party finds most arousing.
Caution: Do not attempt if consuming partner is lactose intolerant, allergic to milk products, or infected with the rabies virus.
