WAM
Wet And Messy sex. Describes a fetish of sorts that envolves getting covered with some form of goopy messy substance. This can be either food, such as eggs, chocolate sauce, pancake batter, truffle oil, etc. Or a non-food delight like mud, sweet crude oil, plaster and the like. To me this should be the normal porn material, and freaky "dry and clean sex" would be a fetish.
Sweetheart, did you get the groceries?
Yes, and I picked up corn syrup and veal pate, and an extra shower curtain for our WAM night
