Muff Slush Surprise

The act of a middle aged women of a moderate weight sliding down a hill. Her pants and underwear must be off, and the hill has to have frigid temperatures and dew must still be on the ground. Upon sliding down, the dew from the hill has collected in the pubical regions of the woman's crotchal area. After obtaining the excess collection, it may be used as spread on various delicacies. Examples include bread, cakes, funnel cakes, cupcakes, cookies, muffins, bagels, salads, and sandwiches.

Mary took advantage of Jim's wedding and made her infamous "Muff Slush Surprise Upside Down Cake."
The guests loved her special topping.
