Masturbating. The female version of the phrase "belting the hog," since a woman's clitoris is pink like a piglet and less aggression is implied in the cute alliterative phrase.
I sometimes rag on my boyfriend for how much he belts the hog, but I'd sure be embarrassed if he knew how much of my week I spend patting the piglet.
