Noun: a sexual/sensual food exchange, in which at least one person covers another person in foods of different tastes, textures, and temperatures. Eating the food off said person is optional. It is common practice for the "sploshee" to be nude so as to heighten the feeling of the food on their bare skin. The "splosher" can be nude or clothed based on preference. Other common usages are the present verb splosh.
"He knelt in the shower while his partner covered him with layer after layer of sticky syrups, slick oils, and chilled liquids. Never knowing what sensation or intoxicating aroma she would be sploshing him with next, each touch of her hand or dribble of liquid sent waves of awareness shooting through his body."
