Sure, it’s a bit irreverant. And probably not something I want to explain to my 9-year-old daughter. But it’s doing what it means. The act of putting lipstick on a pig, by it’s very nature, means to fancify something unpleasant. And that something here is lipstick on the unexpected end of said pig. So in the end (pun intended) you get cosmetics that do a rather poor job of being…cosmetic.
