We've never heard anyone refer to their quiet, solitary sex toy time as "pussy mash," but we could totally get behind it. It reminds us of our favorite things: sour mash and mashed potatoes. Not necessarily the most erotic things to associate with self-sexing, but we're open to new experiences.
Maybe this term will take off and people will start calling it "mashturbation." It sounds annoying now, but ten years in the future, it's the only way people pronounce it! How odd it is to think that the O.E.D. will someday be changed due to a super hot girl writhing on her bed in mashturbatory ecstasy.
